John A. Balcerzak (born 1957) is an American former police officer from Milwaukee, Wisconsin. Balcerzak and Joseph T. Gabrish gained national attention in 1991, when they were suspended with pay and later fired for having handed over an injured 14-year-old boy to serial killer Jeffrey Dahmer despite bystanders' protests, as well as for the homophobic remarks made by the officers during the incident. The officers appealed their termination and were subsequently reinstated with back pay of $55,000 each by Judge Robert J. Parins. Balcerzak served as president of the Milwaukee Police Association (the police union for Milwaukee officers) from 2005 to 2009. Balcerzak retired from the Milwaukee Police Department in 2017.
