The United Socialist Party of Venezuela (Spanish: Partido Socialista Unido de Venezuela, PSUV) is a left-wing to far-left socialist political party which has been the ruling party of Venezuela since 2010. It was formed from a merger of some of the political and social forces that support the Bolivarian Revolution led by President Hugo Chávez. It is the largest political party in Venezuela and the 11th largest in the world with more than 7 million active members as of 2014.
At the 2015 parliamentary election, PSUV lost its majority in the National Assembly for the first time since the unicameral legislature's creation in 2000 against the Democratic Unity Roundtable, winning 55 out of the National Assembly's 167 seats. In the 2020 elections however, amid a widespread opposition boycott, they won back a supermajority of the chamber.
