What is the name of the charitable trust created by Walmart's founding family, the Waltons?

The charitable trust created by Walmart’s founding family, the Waltons, is the Walton Family Foundation.

Sam Walton and his wife, Helen Walton, established the foundation in 1987 with an initial gift of $1,000. After Sam Walton died in 1992, he transferred $172 million to the foundation through a trust, greatly expanding its resources.

The foundation is a private family foundation headquartered in Bentonville, Arkansas. Its major areas of work include education, environmental conservation—especially water-related issues—and community development in Northwest Arkansas and the Arkansas-Mississippi Delta.

A common mix-up is the Walmart Foundation, which is Walmart’s corporate philanthropy arm. The Walton Family Foundation is a separate organization funded and directed by members of the Walton family. Its grants have supported charter schools, education reform, river and watershed conservation, and regional economic initiatives.
