Péter Kovács (born January 11, 1934 in Szolnok – December 1, 1968 in Szeged), known as the "Martfu Monster", was a Hungarian rapist and serial killer who attacked vulnerable women on the streets at night around the southern settlements of Szolnok.
The case surrounding his murder series is considered to be one of the biggest professional mistakes of Hungarian law enforcement at the time, as an innocent man was initially condemned for them.
