Leslie Charles "Les" Nimmo (23 February 1897 – 6 November 1972) was an Australian politician who was a Liberal Party member of the Legislative Assembly of Western Australia from 1947 to 1956 and again from 1959 to 1968.
He served with the Royal Australian Navy during World War I, and on his return to Hobart worked as a shop assistant.
[1] He entered parliament at the 1947 state election, narrowly winning the inner-city seat of Mount Hawthorn from the Labor Party.
A Labor candidate, Frederick Marshall, also won in Wembley Beaches, but Nimmo reclaimed that seat at the 1959 election.
However, Wembley Beaches was abolished prior to the 1962 election, forcing another change of seats to the new Karrinyup electorate.
