First Liberty Institute is a nonprofit Christian conservative legal organization based in Plano, Texas.

Prominent in legal circles on the Christian right, the organization litigates in First Amendment cases on religion, and is often referred to as a law firm.

First Liberty Institute is headed by Kelly Shackelford who founded the organization in 1997 under the name Liberty Legal Institute. The organization changed its name to Liberty Institute in 2009 and then, in 2016, to First Liberty Institute.

First Liberty Institute is a member of the advisory board of Project 2025, a collection of conservative and right-wing policy proposals from the Heritage Foundation to reshape the United States federal government and consolidate executive power should the Republican nominee win the 2024 presidential election.
