Boyz II Men, American vocal quartet that emerged in the 1990s and became one of the most successful rhythm-and-blues groups, dominating the charts during the first half of the decade. The principal members were Nathan Morris (in full Nathan Bartholomew Morris; b. June 18, 1971, Philadelphia, Pennsylvania, U.S.), Michael McCary (in full Michael Sean McCary; b. December 16, 1971, Philadelphia, Pennsylvania, U.S.), Shawn Stockman (in full Shawn Patrick Stockman; b. September 26, 1972, Philadelphia, Pennsylvania, U.S.), and Wanya Morris (in full Wanyá Jermaine Morris; b. July 29, 1973, Philadelphia, Pennsylvania, U.S.).

The members of Boyz II Men grew up in separate neighbourhoods of Philadelphia and came together as high-school friends at the Philadelphia High School for the Performing Arts, where they studied classical music and vocal arts. The name Boyz II Men came from a song that had been recorded by the pop quintet New Edition. In 1989 the quartet managed to meet Michael Bivins—who had been a member of New Edition—and gave him an impromptu audition. Bivins later signed on as their manager and helped define their gentlemanly image.
