Amy Vivian Coney Barrett (born January 28, 1972) is an American lawyer and jurist who serves as an associate justice of the Supreme Court of the United States. The fifth woman to serve on the court, she was nominated by President Donald Trump and has served since October 27, 2020. Barrett was a U.S. circuit judge on the U.S. Court of Appeals for the Seventh Circuit from 2017 to 2020.

Barrett graduated from Rhodes College before attending Notre Dame Law School, earning a J.D. in 1997 ranked first in her class. She then clerked for Judge Laurence Silberman and Justice Antonin Scalia. In 2002, Barrett joined the faculty at Notre Dame Law School, becoming a professor in 2010. While serving on the federal bench, she has continued to teach civil procedure, constitutional law, and statutory interpretation.

On September 26, 2020, Trump nominated Barrett to succeed Ruth Bader Ginsburg on the Supreme Court of the United States. Her nomination was controversial because the 2020 presidential election was only 38 days away and Senate Republicans had refused to hold hearings for Merrick Garland during an election year in 2016. The next month, the U.S. Senate voted 52–48 to confirm her nomination, with all Democrats and one Republican in opposition.

Described as a protégée of Justice Antonin Scalia, Barrett supports textualism in statutory interpretation and originalism in constitutional interpretation. She is generally considered to be among the Court's conservative bloc.
