The Libertarian Party of Indiana is the Indiana affiliate of the Libertarian Party.

The founding meeting of the Libertarian Party of Indiana was held on July 14, 1974, at the Holiday Inn at Weir Cook Airport (now called the Indianapolis International Airport). Approximately 20–25 people attended including Paul Hyatt, Tom Duncan, Marvin Lazaro, Brian Bernstein, Dick Smith, Steve Butterbaugh, and Charlie Reisert. Reisert made the motion to start the Libertarian Party of Indiana. The first headquarters was located at 1430 N. Capitol Avenue in Indianapolis. The LPIN became a minor political party in 1994 after achieving ballot access when Steve Dillon received more than 2% of the vote running for Secretary of State.

In 2008, the Libertarian presidential ticket of Bob Barr and Wayne Allyn Root had their strongest showing in Indiana, receiving 1.1% of the vote (19,243 votes).^[2] The party's best finish in a statewide race came in 2006 when US Senate candidate Steve Osborn received about 13% of the vote.^[3] Osborn had the best result for a third-party candidate running for the Senate in the 2006 elections.

• Donald Rainwater was the 2020 LPIN nominee for Governor for Indiana. He lost to incumbent Governor Eric Holcomb, but he made a huge impact in the election having received 11.4% (345,567 votes) of the vote after polling as high as 25%. His success has invigorated the Libertarian Party of Indiana, especially in the light of his 2nd-place finish in 1/3 of the 92 counties. Their motto in the 2021 convention, "Level Up" has inspired them to make serious moves to be a party of contention in Indiana politics.^[23]
