Janet Marie DiFiore (born August 9, 1955) is an American judge who since 2016 has been the Chief Judge of the State of New York. A New York native, DiFiore graduated from Long Island University and St. John's University School of Law. As a practicing attorney, DiFiore worked in a law firm and in the Westchester District Attorney's Office. DiFiore then was elected a judge of the Westchester County Court, and was subsequently named a justice on the New York Supreme Court (the state trial court in New York), serving in that post from 2003 to 2005. DiFiore left the bench to become district attorney of Westchester County, New York in 2006; she stayed in that position nearly a decade, until Governor Andrew Cuomo appointed her to the New York Court of Appeals.
