The 30 most generous celebrities

The Giving Back Fund has compiled a list of the celebrities who have made the largest personal public donations to charity in 2006. You can check out the group's methodology on their website.

No big surprise that Oprah Winfrey topped the list with over $58 million. Lance Armstrong, Dolly Parton, and Elizabeth Taylor all tied for 28th place after each giving $500,000.

The Giving Back Fund was established in 1997 and on its website, they describe themselves as hoping, "to serve as the premier philanthropic resource to the sports and entertainment communities. We provide philanthropic advice, management, and mentoring to help encourage responsible, authentic, and effective charity."
