The 1917 New South Wales state election was held on 24 March 1917. This election was for all of the 90 seats in the 24th New South Wales Legislative Assembly and it was conducted in single-member constituencies with a second ballot if a majority was not achieved on the first. The 23rd parliament of New South Wales was dissolved on 21 February 1917 by the Governor, Sir Gerald Strickland, on the advice of the Premier William Holman.
