Paul Moore Jr. (November 15, 1919 – May 1, 2003) was a bishop of the Episcopal Church and former United States Marine Corps officer. He served as the 13th Bishop of New York from 1972 to 1989.

Paul Moore was a graduate of St. Paul's School and Yale University, where, like his father, he was a member of Wolf's Head Society. He had been president of the Berkeley Association, the Episcopal student group, and a Boy Scout leader at Yale.

He was a member of one of America's richest families. Moore was senior fellow on the Yale Corporation from the mid-1960s through the presidential administration of George H. W. Bush.

Moore joined the Marine Corps in 1941. He was a highly decorated Marine Corps captain, a veteran of the Guadalcanal Campaign during World War II earning the Navy Cross, a Silver Star and a Purple Heart. Returning home after the War, Moore was ordained in 1949 after graduating from the General Theological Seminary in New York City. Moore was named rector of Grace Church Van Vorst, an inner city parish in Jersey City, New Jersey, in the former township of Van Vorst, where he served from 1949 to 1957. There he began his career as a social activist, protesting inner city housing conditions and racial discrimination. He and his colleagues reinvigorated their inner city parish and were celebrated in the Church for their efforts.

In 1957, he was named as the dean of Christ Church Cathedral in Indianapolis, Indiana. Moore introduced the conservative Midwestern capital to social activism through his work in the inner city. Moore served in Indianapolis until he was elected Suffragan Bishop of Washington, D.C., in 1964.

During his time in Washington he became nationally known as an advocate of civil rights and an opponent of the Vietnam War. He knew Martin Luther King Jr., and marched with him in Selma and elsewhere. In 1970, he was elected as coadjutor and successor to Bishop Horace Donegan in New York City. He was installed as the bishop of the Diocese of New York in 1972 and held that position until 1989.

Throughout the 1970s, Moore oversaw the diocese's covert (and likely unwitting) support of the FALN, a terrorist group operating in the city in support of Puerto Rican independence. FALN members received tens of thousands of dollars from the diocese and were allowed to utilize church property, including a safehouse in Greenwich, Connecticut. When FBI agents began to investigate FALN's ties to the Episcopal Church, Moore directed legal resources to stymie the effort, denouncing the investigation as a ploy to prevent "the church from funding progressive Hispanic groups."

Moore was widely known for his liberal activism. Throughout his career he spoke out against homelessness and racism. He was an effective advocate of the interests of cities, once calling the corporations abandoning New York "rats leaving a sinking ship". He was the first Episcopal bishop to ordain an openly homosexual woman, Ellen Barrett as a priest in the church. In his book, Take a Bishop Like Me (1979), he defended his position by arguing that many priests were homosexuals but few had the courage to acknowledge it. His liberal political views were coupled with fierce traditionalism when it came to the liturgy and even the creed. In his writings and sermons he sometimes described himself as "born again", referring to his awakening to a fervent Christocentric faith as a boarding school student.
