The 2017 Liechtenstein general election was held on 5 February 2017 to elect the 25 members of the Landtag. It was the 47th legislative term, and ended on 7 February 2021.
The Landtag consists of the elected members, who then elect the president and the government. Of the 25 elected, 11 were newcomers, and 3 were women. Under the composition, the Progressive Citizens' Party (FBP) held nine seats and the Patriotic Union (VU) held eight. As a result, the two parties formed a coalition government under Adrian Hasler of the FBP.
In August 2018, The Independents (DU) Landtag member Erich Hasler was expelled from the party. Fellow Landtag members Thomas Rehak and Herbert Elkuch left the DU in opposition to the expulsion. The following month the three men formed the Democrats for Liechtenstein, and represented the party in the Landtag from then on.
