The Ralph M. Parsons Foundation is an independent grantmaking philanthropy based in Los Angeles that strives to support and facilitate the work of the region's best nonprofit organizations, recognizing that many of those in need today will go on to shape the future of Southern California, to define it, redefine it, and help it set and achieve new goals.

The foundation was established in 1961 by the late Ralph M. Parsons, founder of the international engineering and construction firm that bears his name. The foundation awards grants focusing on the areas of higher education, social-impact programs, health, and civic and cultural endeavors.
