Lawnside is a Borough in Camden County, New Jersey, United States. As of the United States 2010 Census, the borough population was 2,945.
The land that became Lawnside was purchased by Abolitionists for freed and escaped slaves, as well as other African Americans, in 1840.
On April 20, 1926, an "Official Special Election" was held in the Borough of Lawnside. Just one month earlier, on March 24, 1926, Governor of New Jersey A. Harry Moore signed into law New Jersey General Assembly Bill 561, dissolving Centre Township, of which Lawnside was a part, and incorporating the Borough of Lawnside, which also included portions of the borough of Barrington. With its first election, Lawnside became the first independent self-governing African American community north of the Mason-Dixon line.
