James Joseph Garrigan (26 May 1905 – 5 April 1971) was an Australian trade unionist and politician who served as a Labor Party member of the Legislative Council of Western Australia from 1954 until his death, representing South-East Province.
After leaving school, he lived in New South Wales for a period, working variously as a farmer, horse breaker, shearer, and station overseer.
Garrigan moved to Kalgoorlie-Boulder in 1929 to work on the mines, and eventually became an underground supervisor.
He served on the executive and management committee of the Australian Workers' Union's mining division.
He died in office just over a month before his final term would have ended.
