The Łódź Gay Murderer is an unidentified Polish serial killer who operated in Łódź from 1988 to 1993. He murdered seven men, all of them homosexuals.

From 1988 to 1993, a series of murders took place in Łódź. All victims were connected by the fact that they were gay, died in their own flats and right after or during sexual intercourse. The perpetrator stole, among other things, TVs, videos, jewelry, cash and other items from the apartments of the murdered men. The victims died by strangling, stabbing or being beaten to death. The murders were not planned because the instruments of the crime were objects from the victims' flats.^[1]

At the turn of the 1980s and 1990s in the larger cities, Polish gay men would cruise around looking for new social contacts.^[2]

After the last murder, committed in July 1993, an important witness appeared, who had sex with a young man named Roman. The witness met with Roman the previous day, where they went to Kazimierz K.'s apartment. When all the guests left, the host and Roman stayed in the apartment. The following day, Kazimierz K. was found dead. The witness who brought Roman to the victim's home testified that he had told him a lot about himself. The young man said that he was raped by an educator from the reformatory when he was 15. He was supposedly working in the Eskimo cotton industry and lived with his mother in the area of Rzgowska Street. He was 27 years old, 1.78 m tall, with hazel eyes and dark blond hair combed to the side. He also had tattoos: a dot with a left eye, a laryngeal dot and letters on the fingers on the left hand.^[4]

In 2007, policemen from the Łódź Archives took interest in the murder series.^[5]
