Cynthia Jenkins (July 21, 1924 – October 31, 2001) was an American librarian, community activist, and politician from New York.
On April 17, 1949, she married Joseph D. Jenkins (1921–2011), a World War II U.S. Army veteran and insurance broker.
In 1997, she tried to challenge the incumbent New York City Councilman Archie Spigner in the 27th District's Democratic primary, but was ruled off the ballot.
A large part of the signatures of her petition were rejected by Justice Joseph G. Golia of the New York Supreme Court which left Jenkins with less than the required number of 900 registered Democrats who needed to sign.
She died on October 31, 2001, in North Shore Hospital in Manhasset, New York, after a long illness; and was buried in Louisville, Kentucky.
