Ilocos Norte (lit. 'Ilocos North'), officially the Province of Ilocos Norte (; ), is a province of the Philippines located in the Ilocos Region. It is located in the northwest corner of Luzon Island, bordering Cagayan and Apayao to the east, and Abra to the southeast, and Ilocos Sur to the southwest. Ilocos Norte faces the South China Sea to the west and the Luzon Strait to the north. Its capital is Laoag City, which is the most populous in the province.
Ilocos Norte is noted for its distinctive geography and culture. This includes numerous examples of well-preserved Spanish colonial era architecture, particularly Saint William's Cathedral in Laoag with its sinking bell tower done in the Earthquake Baroque style, the St. Augustine Church in Paoay which is one of UNESCO's World Heritage Sites in the Philippines, and the Cape Bojeador Lighthouse. Famous geographical features include the La Paz Sand Dunes, the beaches of Pagudpud, and the eroded calcarenite Kapurpurawan rock formation in Burgos. 
It is the birthplace of several notable Philippine leaders including former President Ferdinand E. Marcos, Philippine Revolutionary War general Artemio Ricarte and Iglesia Filipina Independiente co-founder Gregorio Aglipay. 
Three wind farms are located in Ilocos Norte. They are located in Burgos, Pagudpud and Bangui with the latter being the first wind power generation plant in the Philippines.

History.
Early history.
Long before the arrival of the Spaniards, there existed an extensive region consisting of Ilocos Norte, Ilocos Sur, Abra and La Union. Merchants from Japan and China would often visit the area to trade gold for beads, ceramics and silk. The Austronesian inhabitants of the region called their place "samtoy", from "sao mi toy", which literally meant "our language".
Spanish colonial era.
In 1571, the Spanish conquistadors had Manila under their control and they began looking for new sites to conquer. Miguel Lopez de Legazpi's grandson Juan de Salcedo volunteered to lead one of these expeditions. Together with 8 armed boats and 45 men the 22-year-old voyager headed north. On June 13, 1572, Salcedo and his men landed in present-day Vigan then proceeded to Laoag, Currimao and Badoc. As they sailed along the coast they were surprised to see numerous sheltered coves ("looc") where the locals lived in harmony. They named the region "Ylocos" and its people "Ylocanos".
As the Christianization of the region grew so did the landscape of the area. Vast tracts of land were utilized for churches and bell towers in line with the Spanish mission of "bajo las campanas". In the town plaza it was not uncommon to see garrisons under the church bells. Indigenous peoples living in the Ilocos Region, such as the Yapayao and Isneg, were slowly pushed into living in the sparsely populated but resource-rich mountains, which would expose them to conflicts with developers in later eras, such as during Martial Law under Ferdinand Marcos.47
Spanish colonization of the region was not completely successful. Owing to the abusive practices of many Augustinian friars a number of Ilocanos revolted. Noteworthy of these were the Dingras uprising (1589) and the Pedro Almasan revolt (San Nicolas, 1660). In 1762, Diego Silang led a series of battles aimed at freeing the Ilocano. When he died from his friendly fire his widow Gabriela continued his cause. She too was captured and executed.
In 1807 the sugar cane ("basi") brewers of Piddig rose up in arms to protest the government's monopoly of the wine industry. In 1898, the church excommunicated Gregorio Aglipay for refusing to cut off ties with the revolutionary forces of Gen. Emilio Aguinaldo. Unperturbed, he helped established the "Iglesia Filipina Independiente".
In an effort to gain political control and because of the increasing population of the region, a Royal Decree was signed on February 2, 1818, splitting Ilocos into two provinces: Ilocos Norte and Ilocos Sur. Soon thereafter, La Union and Abra became independent provinces.
Japanese occupation.
After the fall of Corregidor and the subsequent occupation of the Philippines by the Empire of Japan, a number of small guerrilla groups formed in the area of Ilocos Norte, some of which resorted to banditry. Governor Roque Ablan Sr., with the help of Philippine Army Lt. Feliciano Madamba, was able to put together a guerrilla unit to engage the Japanese forces and to rally the other guerrilla groups into a common force. The leaders were assigned specific sectors using a system for distributing news and orders.
Philippine independence.
The decade after the recognition of Philippine independence marked a return of the tobacco industry to Ilocos Norte. Ever since the end of the tobacco monopoly, tobacco production had declined in the Ilocos as Filipinos started shifting from locally made cigars to foreign made cigarettes. But after reading a feature article series by Maximo Soliven which explained why Virginia tobacco would grow well on Ilocos soil, businessman Harry Stonehill was convinced to invest extensively in rebuilding the industry, establishing the Philippine Tobacco Flue-Curing and Redrying Corporation (PTFCRC) in 1951 and recruiting farmers from throughout Region 1 to produce tobacco. The following year, La Union Congressman Manuel T. Cases filed a bill to "limit the importation of foreign leaf tobacco," which was eventually signed by President Elpidio Quirino as Republic Act 698. This allowed Stonehill's investments to make a handsome profit, and the newly-rebuilt local industry to bloom. Stonehill was later deported a decade later, in the 1960s, for tax evasion and bribery of government officials, in what would later be called the Stonehill scandal, but the tobacco industry continued to grow.
During the Marcos dictatorship.
Ilocos Norte gained additional prominence in December 1965 when Ferdinand Marcos became president, and again when he won a second term in 1969, boosted by debt-driven infrastructure spending that created economic crises and massive social unrest at the beginning of the 1970s. Facing the end of his constitutionally allowed presidential terms, he declared martial law in 1972 and became dictator under a system of constitutional authoritarianism for fourteen more years. His family and cronies were accused of stealing an estimated US$5 billion to US$10 billion during the 1980s, when the Philippine economy sharply declined until Marcos was deposed by the civilian-led People Power Revolution of February 1986.
Various human rights violations were documented in the Ilocos Norte region during the Marcos martial law era, despite public perception that the region was supportive of Marcos' administration. Various farmers from the towns of Vintar, Dumalneg, Solsona, Marcos, and Piddig were documented to have been tortured, and eight farmers in Bangui and three indigenous community members in Vintar were "salvaged" in 1984.
There were also various protests against the Marcos administration at the time, with Aurora Park in the Laoag Plaza being one of the favored places to stage protests. One of the prominent victims of the Martial Law era who came from Laoag was Catholic layperson and social worker Purificacion Pedro, who volunteered in organizations protesting the Chico River Dam Project in the nearby Cordillera Central mountains. Wounded while visiting activist friends in Bataan, she was later killed by Marcos administration soldiers while recuperating in the hospital. Another prominent opponent of the martial law regime was human rights advocate and Bombo Radyo Laoag program host David Bueno, who worked with the Free Legal Assistance Group in Ilocos Norte during the later part of the Marcos administration and the early part of the succeeding Aquino administration. He would later be assassinated by motorcycle-riding men in fatigue uniforms on October 22, 1987 – part of a wave of assassinations that coincided with the 1986–87 coup d'état that tried to unseat the democratic government set up after the 1986 People Power Revolution. Both Bueno and Pedro were later honored among the first 65 people to have their names inscribed on the Wall of Remembrance of the Philippines' Bantayog ng mga Bayani, which honors the martyrs and heroes who fought the dictatorship, and Pedro was listed among Filipino Catholics nominated to be named Servant of God.
Contemporary.
The municipality of Batac became a component city by virtue of "Republic Act No. 9407" which sought to convert the municipality into a city. The law was ratified on June 23, 2007. However, the cityhood status was lost twice in the years 2008 and 2010 after the LCP questioned the validity of the cityhood law. The cityhood status was reaffirmed after the court finalized its ruling on February 15, 2011 which declared the cityhood law constitutional.
Ilocos Norte was among the provinces affected by the COVID-19 pandemic in the Philippines, reporting its first three cases of COVID-19 on March 31, 2020, including a male patient each from Batac and Paoay, and former senator Bongbong Marcos, who had arrived from travel to Spain. Ilocos Norte experienced surges in cases in 2021, with the spike reported in August 2021 being attributed to the Delta variant of the virus.

Ilocano is also recognized as a minority language in Mindoro, Palawan and Mindanao (particularly in some areas in Soccsksargen), where Ilocanos had have been significant residents since the early 20th century. It is a third most widely spoken language in the Philippines, estimating 11 million speakers as of 2022. The language has many speakers overseas, including the American states of California and Hawaii. Filipino/Tagalog and English are also spoken and understood in the region, utilized in business, education and media.

Bangui Wind Farm.
In 2005, NorthWind Power Development Corp. began commercial operation of the Bangui Wind Farm in the Municipality of Bangui, having initiated and developed the project in response to a 1996 study by the National Renewable Energy Laboratory (NREL) which identified Bangui as one of the viable sites for wind energy sites in the Philippines. Connected to the Luzon Grid, the project was
the first wind farm in Southeast Asia, supplying 40% of Ilocos Norte's electricity needs, and becoming a major tourist site for Bangui. AC Energy, the listed energy platform of the Ayala Group, acquired the controlling shares of Northwind and of the Bangui Wind Farm in 2017.
