Gerald H. Zecker (born April 12, 1942) is an American Republican Party politician who served 18 years in the New Jersey General Assembly, from 1984 to 2002, where he represented the 34th Legislative District, losing office after several heavily Democratic communities were added to his district in the 2001 apportionment following the 2000 United States Census. He served as mayor of Clifton, New Jersey from 1978 to 1982. In 1990, Zecker questioned the viability of the construction of the 20-mile long Passaic River Flood Tunnel, saying that it could "be the biggest mistake we've ever made".
