Mary L. Bonauto (born 1961) is an American lawyer and civil rights advocate who has worked to eradicate discrimination based on sexual orientation and gender identity, and has been referred to by U.S. Representative Barney Frank as "our Thurgood Marshall" She began working with the Massachusetts-based Gay & Lesbian Advocates & Defenders (GLAD) organization in 1990. A resident of Portland, Maine, Bonauto was one of the leaders who both worked with the Maine legislature to pass a marriage equality law and to defend it at the ballot in a narrow loss during the 2009 election campaign. Bonauto is known for being lead counsel in the case Goodridge v. Department of Public Health which made Massachusetts the first state in which same-sex couples could marry in 2004. She is also responsible for leading the first strategic challenges to section three of the Defense of Marriage Act (DOMA). Bonauto argued before the U.S. Supreme Court in the Obergefell v. Hodges case on April 28, 2015, on behalf of same-sex couples seeking marriage rights.

This much-publicized case determined that state bans against same-sex marriage are unconstitutional and is considered one of the most important civil rights cases which came before the U.S. Supreme Court in modern history. She will always be remembered as the lawyer who represented the plaintiff, Jim Obergefell, in the same-sex marriage case victory that made history on June 26th 2015. Obergefell, the main plaintiff in the landmark case, started the lawsuit with 30 other plaintiffs because of his husband, John. When John died from ALS, the state of Ohio would not allow Obergefell's name to be on his death certificate.
