Jefferson Diggs (d. 2010) was a Civil Rights activist who lived in Jamaica, Queens with his wife Sonia Geder for more than 40 years.

Born in West Virginia, Diggs moved to Ohio, where he attended high school and wrote for a local Black newspaper, the Ohio State Sentinel. He enrolled at Winston Salem State Teachers College, where he was moved by the injustices of racism and segregation, joined the Civil Rights movement and participated in the first wave of sit-ins at Woolworth and Kress lunch counters.

After graduating, Diggs was hired as one of the first African-American reporters by The New York Daily News. In 1983, he started working for former Councilmember Archie Spigner as a part-time legislative aide and subsequently for his successor, current Councilmember Leroy Comrie.

Diggs was active in his community and was a founding member of the Elmer Blackburne Regular Democratic Club and a member of the Guy Brewer Democratic Club, Jamaica NAACP, Omega Psi Phi Fraternity Inc., the Black Heritage Board and Community Board 12. He was also an active member of Immaculate Conception R.C. Church.
