1915 Queensland state election

Elections were held in the Australian state of Queensland on 22 May 1915 to elect the 72 members of the state's Legislative Assembly.

The election was the second for the Liberal government of Digby Denham, who had been premier since 7 February 1911. The opposition Labor Party, led by T. J. Ryan, had two previous Premiers — Anderson Dawson in 1899 and William Kidston in 1906 — but the former did not command a majority of parliamentary support, while the latter maintained it by splitting the Labor Party. Labor had never before held majority government.

The election was the first in Australia to be conducted using compulsory voting due to Denham's concern that Trade Unions were effectively mobilising the ALP vote; he felt that compulsory voting would ensure a more level playing field. However, it turned out that the change to compulsory voting was not enough to save Denham's premiership.

The election resulted in the defeat of the government, and Queensland's first majority Labor government. All except two members of the Ministry up for election, including Denham himself, lost their seats.

Results
The election saw a landslide to Labor from the 1912 election.
