Phil Penna (November 1857 – 5 January 1939) was an American labor leader, and president of the United Mine Workers of America (UMWA) from 1895 to 1896.
John McBride, president of UMWA, had won election as president of the American Federation of Labor in 1895, unseating Samuel Gompers.
McBride resigned to take the position, and Penna was elected his successor.
During Penna's presidency, membership in the Mine Workers fell from 13,000 to 9,700, and the union's treasury dropped from $2,600 to $600.
