John Carr (15 July 1871 – 6 June 1929) was a union leader and politician in South Australia.
[1] At an early age he took an active interest in the Labor movement, and was on several occasions president of the Working Men's Association, then secretary, holding that post for twelve years.
During his period as an official there was little industrial disputation in the workplace, largely due to his tact and good judgment.
His brother, William H. Carr of Albert Park, was for several years a leading amateur swimmer at Port Adelaide.
Another brother, Frederick Alfred Carr of Finsbury Park, was secretary of the Port Adelaide branch of the Waterside Workers' Federation, and mentioned as a possible replacement on the Legislative Council,[3] a safe Labor seat, but it was Stanley R. Whitford who won the plebiscite.
