The Tykocin massacre (pogrom), of August 25, 1941, was the mass murder of Jewish residents of Tykocin in occupied Poland during World War II, soon after the Nazi German attack on the Soviet Union.

Upon their arrival, the Nazi Germans encouraged the local Poles from Tykocin and the surrounding villages to loot Jewish property, which they later ordered to be given back to their so-called "proper owners" (a common tactic used by the Nazis to persecute the Jewish people), for the Germans' own anticipated benefit. On the morning of August 25, 1941 – according to a testimony of Abraham Kapice – as explained also by the Jewish and Polish memorials on the outskirts of town, the Germans ordered all Tykocin Jews to gather at the market square in order to be "resettled" to a ghetto in Czerwony Bór. About 1,400–1,700 people were soon taken from the square to a killing site in the nearby ?opuchowo forest. The men were marched on foot, and the women with children were trucked in. Some local Jews managed to escape into hiding, though very few survived. The prisoners, including women, children, and the elderly, were executed in waves into the execution pits, by an SS Einsatzkommando firing squad under the command of SS-Obersturmführer Hermann Schaper.
