Mary D. Carter (1930-1988) was a community activist and longtime resident of the Boulevard Gardens apartment complex in Woodside. As Director of the Boulevard Gardens Tenants Association, she arranged entertainment for local children and trips for senior citizens living in the complex. Carter worked for Congresswoman Geraldine Ferraro and was involved with the Liberty Democratic Club, the Police Athletic League of the 114th Precinct, the American Legion Auxiliary, the Lexington School for the Deaf, and the Corpus Christi School and Church. She was also active in the Girl Scouts, where she served as both a Brownie and Girl Scout Leader. She was married to the late Charles Carter and had four children.

The renaming of P.S. 151 in honor of Carter was recommended by the school's Parent Association, which described her as "a perfect role model" for the school community.
