The1917 Australian federal election was held in Australia on 5 May 1917. All 75 seats in theHouse of Representatives and 18 of the 36 seats in theSenate were up for election. The incumbentNationalist Party, led by Prime MinisterBilly Hughes, defeated the oppositionLabor Party led byFrank Tudor in a landslide.

Hughes, at the time a member of the ALP, had become prime minister whenAndrew Fisher retired in 1915. TheAustralian Labor Party split of 1916 overthe conscription issue had led Hughes and 24 other pro-conscription Labor MPs to split off as theNational Labor Party, which was able to form a minority government supported by theCommonwealth Liberal Party underJoseph Cook. Later that year, National Labor and the Liberals merged to form the Nationalist Party, with Hughes as leader and Cook as deputy leader. The election was fought in the aftermath of the1916 plebiscite onconscription, which had been narrowly defeated. The Nationalists won a decisive victory, securing the largest majority government since Federation. The ALP suffered a large electoral swing against it, losing almost seven percentage points of its vote share compared with 1914. The swing was magnified by the large number of former Labor MPs who followed Hughes out of the party. This election would be the last federal election using thefirst past the post election system as Australia switched to thepreferential voting system in1919.

This is the first of two elections (the other in 1922 also with Hughes as the incumbent Prime Minister), in which the incumbent Prime Minister, Hughes, had successfully transferred to another seat.

At this election, Hughes had abandoned West Sydney, which he won with 75.3% of the vote as the Labor candidate at the previous election in 1914, and moved to Bendigo instead, winning it as the Nationalist candidate: unlike 1922, Hughes made his seat transfer in 1917 by defeating that seat's incumbent member, Alfred Hampson, for re-election, the only time that an incumbent Prime Minister has defeated another MP for his seat.

Except for the 1917 and 1922 elections, all other elections have seen the incumbent Prime Minister recontest the seat that they held prior to the election.
