Parliamentary elections were held in Venezuela on 6 December 2015 to elect the 164 deputies and three indigenous representatives of the National Assembly. They were the fourth parliamentary elections to take place after the 1999 constitution, which abolished the bicameral system in favour of a unicameral parliament, and the first to take place after the death of President Hugo Chávez. Despite predictions from the opposition of a possible last-minute cancellation, the elections took place as scheduled, with the majority of polls showing the Democratic Unity Roundtable (MUD) holding a wide lead over the ruling United Socialist Party of Venezuela (PSUV) and its wider alliance, the Great Patriotic Pole (GPP).

The United Socialist Party of Venezuela is a left-wing to far-left socialist political party which has been the ruling party of Venezuela since 2007. It was formed from a merger of some of the political and social forces that support the Bolivarian Revolution led by President Hugo Chávez.
