Patrick Laurence Troy (17 January 1908 – 19 April 1978) was an Australian trade unionist and communist activist.
The Troys moved to Fremantle, Western Australia, during World War I, and Paddy attended the local Christian Brothers' College.
[1] The Great Depression was a challenging time for Troy, who spent long periods unemployed with only casual work to support his family.
During his period of activity he was Western Australia's most prominent communist; despite this, he enjoyed the respect of employers and the trust of his union.
He had a pilot boat named after him, and the Perth branch of the Australian Society for the Study of Labour History has an essay competition in his honour.
