Liberal Party of Sierra

The Liberal Party of Sierra (commonly known as the Sierra Liberals) is the branch of the Liberal Party of Enderron operating in Sierra Prefecture. The party is the one of the three major political parties in Sierran politics, the others being the Sierra Social Democrats and the Sierra National Party. The current party leader is Kylie Langford, since 2017.

In contrast with the rest of Enderron, the Liberal Party of Sierra is not significantly stronger than National Party, and the two parties share the right-of-centre of Sierra's political spectrum. The Sierra Liberals are traditionally more centrist than their federal counterparts, with the party's main demographic being middle class urban voters. Its vote is concentrated in the suburbs of Los Prados, the only major metropolitan area in the prefecture, as well as some smaller regional population centres across Sierra.

The Sierra Liberals currently hold the governorship following the 2020 election, in which Danielle Kinsey was elected governor. The party most recently controlled the legislature from 2004 to 2012, under premiers Mark Dennehy (2004–2011) and Gary Seldon (2011–2012).
