Order Sons of Italy in America
The Order Sons and Daughters of Italy in America, formerly the Order Sons of Italy in America (, OSIA) is the largest and the oldest Italian American fraternal organization in the United States. A similar organization exists in Canada.

It has more than 600,000 members and supporters. Since its founding in 1905 it has established more than 2,800 lodges in 43 states, with the headquarters located near Capitol Hill in Washington, D.C.

History
It was founded on June 22, 1905, by Vincenzo Sellaro to help assimilate Italians into American society during the immigration boom of the early 20th century. In 1928 Sellaro was given the key to the City of New York in recognition of his social and medical achievements.

After World War II, the organization faced criticism for the "heavy involvement by the OSIA in Mussolini's Fascist propaganda campaign in the 1920s and 1930s".

OSIA has been involved in promoting immigration legislation, assisting in the assimilation process, supporting cooperation, trade, and diplomatic relations between the United States and Italy, initiating social and fraternal events, encouraging educational achievement through scholarships, serving local communities through a variety of cultural events and raising funds for local charities, and providing low-cost group financial investments and insurance.
