The United Engineering Center was a building in the Turtle Bay neighborhood of Manhattan in New York City that served as the headquarters of several national associations of professional engineers and included an auditorium, exhibition hall, and library. Located on the west side of United Nations Plaza between East 47th and 48th streets—across from the headquarters of the United Nations—the building opened in 1961 and superseded the Engineering Societies' Building, which had become too small for the engineering societies' needs. By the mid-1990s, the United Engineering Center had become inefficient at serving the needs of the organizations it housed; the building was sold and demolished in 1998 in order to make way for the Trump World Tower.
