Mercersburg is a borough in Franklin County, located near the southern border of Pennsylvania, United States. The borough is  southwest of Harrisburg, the state capital. 

Due to its location in a rural area, it had a relatively large percentage of African-American workers who had been enslaved from the Revolution. It was called "Black Town" in the early nineteenth century before incorporation under its current name. Refugee African Americans escaping from slavery in the South also settled here, and the area was known as "Little Africa".

History
Mercersburg was platted in 1780. The borough was named after Hugh Mercer, a general and hero in the American Revolutionary War. A post office has been in operation at Mercersburg since 1812.

Located near the southern border of Pennsylvania, the rural community became a place of refuge during the antebellum years for escaped African Americans who had been enslaved in the South. Some came to the area via the Underground Railroad. After the American Revolution, Pennsylvania had abolished slavery. In this area were communities of free African Americans who had worked in agriculture. It was relatively easy for refugees to join their communities after passing over the border of Maryland. 

This settlement was called "Black Town" in early years, before being incorporated in 1831. The rural area outside of town was referred to by locals as "Little Africa" because of its relatively large concentration of African Americans in this time period. Some were refugees who had settled here after escaping from slavery in the South. 

In later years, black folks moved away from here as they were at risk from slavecatchers, especially after passage of the Fugitive Slave Act in 1850, which had more stringent rules against free states. Many African Americans moved to Philadelphia, which had a large and free black community, which helped new arrivals get settled. Philadelphia also provided more job opportunities.

In 2010, 6.49% of the population was of African American descent, a total of 1,561 persons.

The Mercersburg Historic District, Lane House, and Mercersburg Academy are listed on the National Register of Historic Places.

Education

Tuscarora School District
The Tuscarora School District covers an area of , stretching north-south from just south of 40 degrees north latitude to the Maryland border and from east of the 78 degree west longitude line to just west of Chambersburg. The district is located within the borders of Franklin County in south-central Pennsylvania. It includes the borough of Mercersburg and Montgomery, Peters, St. Thomas and Warren townships. The school district primarily encompasses a rural agricultural area with a total population of approximately 17,000 people. 

The district consists of four K-5 elementary schools (Saint Thomas, Mountain View, Mercersburg, Montgomery), one grades 6-8 middle school (James Buchanan MS) and one grade 9-12 high school (James Buchanan High School). Tuscarora, the name of the mountain on the western boundary, was named for the Tuscarora Nation, an Iroquoian-speaking tribe. They had lived in this area for a period after migrating from the Carolinas about 1713 after disastrous warfare. They continued to migrate north to present-day New York, where about 1722 they declared their migration over. They were accepted as the sixth nation of the Iroquois League, or Haudenosaunee, the powerful confederacy of five nations that occupied much of the territory west of the Hudson River and into northern Pennsylvania. 

Colonists adopted the Lenape language term for Conococheague Creek, which flows through the district on its way from the Path Valley south to the Potomac River. The local Delaware people, properly known as Lenape, named it for "clear water".
