The Themis Fund is a center-left donor collaborative that channels grants from foundations to anti-death penalty litigation nonprofits. The Themis Fund is a project of the Proteus Fund, a major funding and fiscal sponsorship nonprofit.
The Themis Fund provides small grants to support litigation to outlaw capital punishment by judicial decision. Themis has funded litigation demanding better state funding and standards for public defenders, highlighting alleged discrepancies in race and sex on capital prosecutions, showing community opposition to the death penalty to juries, and alleging defendants’ mental illness as a factor in death-penalty cases.

In 2014, the Themis Fund established the 8th Amendment Project, headed by Henderson Hill, specifically to establish a foundation for a Supreme Court decision that would declare capital punishment to be unconstitutional based on the Eighth Amendment’s prohibition of cruel and unusual punishment. The Project supports research on death penalty abolition and aids the defense in capital trials. 
The Themis Fund is a project of the Proteus Fund, a 501(c)(3) nonprofit. As such, grants to and from the Fund are directed through the Proteus Fund and the organization is not required to file annually with the IRS.
