The Gravel Institute (/ɡrəˈvɛl/ grə-VELL) was a progressive left-wing advocacy group founded in 2020 that aimed to counteract American conservative think tanks in general, particularly PragerU.

The Gravel Institute promoted left-wing views, including wealth redistribution, criticism of United States foreign policy, and direct democracy.
