Evan Wolfson (born February 4, 1957) is an attorney and gay rights advocate. He is the founder of Freedom to Marry, a group favoring same-sex marriage in the United States, serving as president until its 2015 victory and subsequent wind-down. Wolfson authored the book Why Marriage Matters: America, Equality, and Gay People's Right to Marry, which Time Out New York magazine called, "Perhaps the most important gay-marriage primer ever written". He was listed as one of Time magazine's 100 most influential people in the world. He has taught as an adjunct professor at Columbia Law School, Rutgers Law School, and Whittier Law School and argued before the Supreme Court in Boy Scouts of America v. Dale. He now teaches law and social change at Georgetown Law School and at Yale University; serves as a senior counsel at Dentons, the world's largest law firm; and primarily provides advice and assistance to other organizations and causes, in the United States and globally, that are seeking to adapt the lessons on "how to win" from the same-sex marriage movement.
