The Libertarian Party of California (LPC) is the California affiliate of the national Libertarian Party (LP). The party chairman is Adrian Malagon, and is based in Sacramento, California, in Sacramento County.^[7] As of 2016 Libertarians represent approximately 0.7% of the state's registered voters.^[8]

In 1972 the party considered suing county clerks in Placer and Butte counties for refusing to allow voters to register as Libertarians.^[9] In 1978 Ed Clark, who had been the affiliate's chairman from 1973 to 1974 and later the national presidential candidate in 1980, ran as an independent for governor of California to gain party recognition and received over five percent.^[10] However, the Secretary of State ruled that the two percent requirement was for retaining party recognition and not gaining party recognition and that since Clark had run as an independent and not a Libertarian it would not count either way.^[11] The party filed a lawsuit against the decision, but it was first dismissed then ruled against on appeal. The Libertarian Party of California has hosted the Libertarian National Convention in 1977, 1979, 1980, and in 2000.

All current Libertarian Party elected officials are in "nonpartisan" elected offices, meaning that the candidates' partisan affiliation is not listed on the ballot.
