United States President Ronald Reagan was the first president to appoint a woman to the Supreme Court.

The story behind the answer

Yes. In 1981, Ronald Reagan fulfilled a campaign promise by nominating Arizona judge Sandra Day O’Connor, making her the first woman to serve on the U.S. Supreme Court. She was confirmed 99–0 and served until 2006, often acting as a pivotal moderate-conservative swing vote.

Remember it this way: Reagan’s first year brought the first woman—“first year, first woman.” O’Connor’s pragmatic approach, including her key role in Planned Parenthood v. Casey (1992), shaped U.S. law for decades and opened the door for future female justices.
