David Joseph Fitzmaurice (1913 – November 12, 1982) was an American labor union leader.
Born in Charleston, Pennsylvania, in the early 1940s, Fitzmaurice began working at General Electric in Cleveland, making light bulbs.
He joined the International Union of Electrical Workers, and soon became a shop steward.
In 1948, he organized an anti-communist slate in his local union; all the members were elected, with Fitzmaurice becoming president.
As leader of the union, he focused on opposing increases in imports and unemployment, and tackling racial and sexual discrimination.
