Freedom Summer, also known as the Freedom Summer Project or the Mississippi Summer Project, was a volunteer campaign in the United States launched in June 1964 to attempt to register as many African-American voters as possible in Mississippi. Blacks had been restricted from voting since the turn of the century due to barriers to voter registration and other laws. The project also set up dozens of Freedom Schools, Freedom Houses, and community centers such as libraries, in small towns throughout Mississippi to aid the local Black population.

Mississippi is a state in the Southeastern region of the United States. It borders Tennessee to the north, Alabama to the east, the Gulf of Mexico to the south, Louisiana to the southwest, and Arkansas to the northwest. Mississippi's western boundary is largely defined by the Mississippi River, or its historical course. Mississippi is the 32nd largest by area and 35th-most populous of the 50 U.S. states and has the lowest per-capita income. Jackson is both the state's capital and largest city. Greater Jackson is the state's most populous metropolitan area, with a population of 591,978 in 2020.
