Thomas Kennedy (November 2, 1887 – January 19, 1963) was a miner and president of the United Mine Workers of America (UMWA) from 1960 to 1963.

Born on November 2, 1887, in Lansford, Pennsylvania, Kennedy started work in the mines at the age of twelve, breaking large chunks of coal into smaller pieces.

He ran for governor four years later, but was defeated when the state Democratic political machine decided not to support him.

In November 1962, Kennedy became too ill to continue his duties and Boyle was named acting president.

Kennedy died on January 19, 1963, in Hazleton, Pennsylvania, and Boyle was elected president as his successor.
