Peter Maass (born 1960) is an American journalist and author.
Maass was born in Los Angeles and graduated from the University of California, Berkeley. He has worked for the Wall Street Journal, the New York Times, the Washington Post, and the New York Times Magazine. He has mainly covered international stories and has lived in Belgium, South Korea, and Hungary. In 1996 he published his first book Love Thy Neighbor: A Story of War. It told of his experiences covering the conflict in Bosnia.
In 1996, Maass wrote an article for U.S. News and World Report which advocated liberalizing zoning laws to promote affordable housing for lower-income families. In the article he praised Jack Kemp for proposing this idea which was later rejected by both the George H. W. Bush and the Bill Clinton administrations.
Two years later, Maass reported on the Unification Church for the New Yorker. He interviewed church members in Korea, the United States and South America, and was one of the few journalists ever permitted to attend church founder Sun Myung Moon's talks to church members.
