The Buck Foundation is a family foundation for support of children and youth, women and minorities with a commitment to peace and social justice.   It was founded by Douglas H. Buck and Mildred M. Buck in 1986 and benefits from continuing involvement and support by their children and grandchildren.

The Buck Foundation focuses on grants for Colorado, especially the Denver Metro area. Some grants have been awarded to national organizations and support for East Maui in Hawai’i.
