New Carrollton is built on the former estate of a horse racing figure, Edward L. Mahoney. After Mahoney's death in 1957, the land was acquired by developer Albert W. Turner, who sought to create a planned suburb. He had received a charter for a City of Carrollton from the Maryland General Assembly four years earlier, on April 11, 1953.
Carrollton was named after early Maryland settler Charles Carroll of Carrollton, a delegate to the Continental Congress and signatory of the Declaration of Independence. As two other Maryland communities were also named Carrollton, a voter referendum on May 2, 1966, approved the renaming of the community to New Carrollton.
New Carrollton is served by the Prince George's County Public Schools.
