The Austrian Parliament (German: Österreichisches Parlament) is the bicameral[1] federal legislature of Austria.

The legislative period lasts five years, elections are held earlier if the National Council prematurely moves for its own dissolution.

Seats are redistributed among the states following each general census, and the overall size of the chamber varies slightly as a result.

The Federal Assembly (Bundesversammlung) is a body whose function is mostly ceremonial in nature, and consists of the members of both houses of Parliament.

It might be noted, however, that under exceptional circumstances the Austrian constitution endows the Federal Assembly with significant responsibilities.
