Geography
Dauphin is located on the western edge of Dauphin County at , on the east bank of the Susquehanna River. The land at the river's edge is alluvial floodplain, but Dauphin sits at the head of a narrow valley between two mountains, at the mouth of Stony Creek. The valley between the two mountains is called Stony Valley, which contains the villages of Singersville and Ellendale Forge. This section along the Susquehanna River is a gateway from the southeastern plains into the Appalachian Mountains and the north-central part of the state. Berrier Island is also located at Dauphin.

Dauphin is surrounded by Middle Paxton Township, which comprises mountains and valleys south of the confluence of the Susquehanna and Juniata rivers. From south to north, the mountains in the township are Blue Mountain, Second Mountain, Third or Stony Mountain, and Peters Mountain. The eastern ends of these valleys are generally undeveloped state game lands and protected watershed.

U.S. Routes 22 and 322 pass through the borough as a four-lane expressway, close to the Susquehanna River, with full access from Pennsylvania Route 225 at the west end of town and with westbound access from the east end of town. US 22/322 leads south  to the center of Harrisburg and northwest  to Duncannon. PA 225 leads north over Peters Mountain  to Halifax.

According to the U.S. Census Bureau, the borough has a total area of , of which , or 1.16%, is water.

History
Dauphin borough began as a settlement at the mouth of Stony Creek, the head of a valley between Second and Third Mountains. It was established by Samuel Sturgeon in 1765. By the end of the eighteenth century, the Sturgeon property was owned by Revolutionary War soldier Timothy Green. The locality became known as Green's Mill, after the grist mill Colonel Green built at the mouth of the creek. According to local history, the area was also known for its colonial-period fort, alternately called Fort Lyon or Fort McKee. Colonel Green continued to hold highly valued real estate until his death in 1812. By 1814, his plantation property with its mills became part of his son Judge Innis Green's holdings. Judge Green continued to add to his real estate holdings throughout the early nineteenth century.

The surrounding township is called Middle Paxton, part of the former Paxton Township of Lancaster County prior to the creation of Dauphin County in 1785. Middle Paxton Township was incorporated in 1787. The main geographic feature of this area are ancient hills or mountains and narrow valleys that generally run east to west with streams emptying into the Susquehanna River. The township remained rural until the twentieth century.

Judge Green laid out Dauphin as "Port Lyon" in recognition of the former fort in 1826. Green named the Port Lyon streets after Pennsylvania rivers and creeks. Opportunities for economic expansion for the area appeared bright that year, as legislation was passed for creation of the Pennsylvania Canal. This fostered expectations that Dauphin would become a port to the coalfields lying to the northeast. Green acted on behalf of the Dauphin & Susquehanna (D & S) Coal Company, which had purchased eighteen tracts of land on or near Little Mountain, totaling about , from a group of businessmen. Charles Bird had earlier that year purchased four tracts of land in Middle Paxton Township from Judge Green. Bird's interest was purchased by a group of businessmen who then sold to the D & S Coal Company. Green received the last payment on the agreement price of US $10,000.00 in 1835.

Dauphin was incorporated into a borough by an act of Assembly in 1845. According to the 1850 census, Dauphin had 650 inhabitants at that time. There were 124 families in 118 dwellings. The 1860 census for the borough illustrated the working-class nature of the people living there. The borough had 649 inhabitants in 129 households, nearly the same as recorded in 1850. Fifty-five of the men listed their occupation as "day laborer". The 1870 census showed a marked change in the occupation of Dauphin's residents. Jobs related to the canal had dropped dramatically, while those associated with the railroads had increased substantially. At this time there were 151 households living in 148 dwellings. The borough's population had increased to 742. By 1875, the borough contained four churches, three schools and one select school, and two lodges. The 1880 census showed 155 families living in 146 dwellings in Dauphin.

In the early twentieth century, several "summer" houses were constructed on the edge of Second Mountain, south of Stony Creek. Middle-class residents of Harrisburg built these houses as second homes to supplement their primary townhouses. These houses are collectively called "Hillside" and have since become year-round homes.

The borough, situated along the Susquehanna River, has always been associated with transportation. Original Native American trails would have followed waterways such as the river and Stony Creek. Development of the canal system of transporting goods during the early nineteenth century gave way to the rise of the railroads, which lasted for much of the twentieth. U.S. Route 22 became a major highway through Pennsylvania during the mid-twentieth century, parts of which were actually constructed within the footprint of the former Pennsylvania Canal. Dauphin thus developed as an early transportation hub, but in more recent decades has been bypassed by more significant routes of transport, such as the Eisenhower Interstate Highway System.

In the last forty or so years, Dauphin Borough has been a bedroom community of Harrisburg, the Pennsylvania state capital. Many of its civic centers had gone into steep decline, industry migrated elsewhere, taverns and hotels closed, as did schools and churches. The railroad, which declined during the late twentieth century, has been reduced to two tracks paralleling the river, with no stops or stations in Dauphin. One of the reasons for the decline was that as traffic on U.S. Rte. 22 increased, the borough became less desirable as a place in which to reside. By the 1980s, traffic on Rte. 22 was so heavy that the road essentially cut the borough in half. Residents often had such a difficult time traveling across the borough that they waited until after morning and evening rush hours. On weekends when the Pennsylvania State University in State College, some  upstate, held football games, Rte. 22 through the borough was impassable.

In older times, Dauphin was the hub of a collection of small village centers in Middle Paxton Township of Dauphin County. Some of these settlements included Singersville, just east of the borough; Ellendale Forge,  up Stony Creek Valley; Dauphin Furnace,  west of town at the mouth of Clark Creek; Speeceville,  west of town at the foot of Peters Mountain; and Heckton Mills, south of Second Mountain about a mile downriver from Dauphin. Much of the eastern part of the township, between Peters Mountain and Second Mountain, is forested and preserved as State Game Lands.

Most of these village centers have ceased to exist as the western part of Middle Paxton Township became suburbanized. The nearest organized towns to Dauphin are Duncannon, a borough on the western shore of the river; Halifax, a borough north of Peters Mountain; and Harrisburg, the state capital to the south.

In the late 1990s, following many years of planning and several postponements, Dauphin Borough was bypassed. A construction project that had caused much controversy resulted in relocating U.S. Rte. 22 closer to the river and out of, or over, Dauphin Borough. Approximately 28% of the borough's taxable real estate was taken in order to construct the bypass. The remaining town, free of the traffic problems, became once again desirable as a location for commuters to Harrisburg. Some of the last remaining open land in the borough was developed as residential space, and older structures in the borough were increasingly bought and renovated by commuters. Despite the losses in tax revenues owing to construction of the bypass, the local government continues to operate through cost-saving, cooperative efforts with Middle Paxton Township. Sewer system connections were extended to borough residents in Hillside and along River Road as part of a collection system and pump station upgrade. In 2011, the Dauphin/Middle Paxton Fire Company relocated its apparatus from the borough to a new government building housing Middle Paxton Township offices and Public Safety. The local ambulance association became dormant, and Susquehanna Township E.M.S. began covering medical emergencies in both borough and township.
