Sărmașu massacre refers to the torture and massacre of 165 people, primarily Jews, committed by Hungarian paramilitaries in Sărmașu, Mureș County. After Romania left the Axis Powers and joined the Allies, between 5 September and 10 October 1944, Sărmașu came under the occupation of the Nazi-aligned Hungarian troops. During this period, Hungarian gendarmes and members of the Hungarian National Guard, led by captain of gendarmes Lánczos László, killed 126 local Jews, as well as 39 Romanians, the latter primarily prisoners of war captured in the battles on the alignment of Oarba de Mureș–Luduș–Gheja–Chețani.
