The legacy of Winthrop Rockefeller lives on in the form of numerous charities, scholarships, and the activities of the "Winthrop Rockefeller Foundation" and the "Winthrop Rockefeller Charitable Trust", including Winrock International, an international nonprofit organization based in Little Rock, Arkansas whose mission is to empower disadvantaged people, increase economic opportunity, and sustain natural resources. The Winthrop Rockefeller Foundation provides funding for projects across Arkansas to encourage economic development, education, and racial and social justice. In 1964, he founded Museum of Automobiles on Petit Jean Mountain, which after his death in 1973 was given to the Arkansas State Parks system; a non-profit organization was formed to run the museum; in March 2007, the Charitable Trust pledged $100,000 for its ongoing operations if the museum raised an equal amount by the end of that year.
