James "Big Jim" Healy (22 March 1898 – 13 July 1961) was an Australian trade unionist and communist activist.
Healy served as General Secretary of the Waterside Workers' Federation of Australia from 1937 to his death in 1961, a period when the union recovered from its defeat in the 1928 waterfront strike to become one of the most powerful trade unions in Australia.
Healy was one of the most prominent public representatives of the communist movement in Australia during the Cold War.
