Treblinka is a small village in the Mazowieckie voivodship (province) of Poland. In 1984 it had 330 inhabitants.

During World War II, Nazis organized the Treblinka extermination camp in the neighbourhood of the village. The camp was opened on July 23, 1942. The majority of the Jews killed here were from the great Jewish community of Warsaw. Estimates of the number of people killed there range from 700,000 to 1,400,000 with over 5,000 sent daily to die in Trelibinka from Warsaw alone.

Treblinka was the name of a Swedish punk rock band. The name was chosen for its shock value, but the band itself never had any connections with Nazis and never backed their ideology.
