Szczuczyn ([ˈʂt͡ʂut͡ʂɨn]; Yiddish: שצוצין, romanized: Shtutzin) is a town in Grajewo County, Podlaskie Voivodeship, Poland.

In 1437, the Szczuka noble family of the Grabie coat of arms purchased the land, on which they founded the village, which was initially named Szczuki-Litwa.

[1] Thanks to the efforts of Stanisław Antoni Szczuka, Szczuczyn was granted town rights around 1690 by Polish King John III Sobieski.

[2] Szczuczyn was a private town, administratively located in the Masovian Voivodeship in the Greater Poland Province of the Polish Crown.

[2] Factors that largely contributed to the development of the town were the presence of the school and the location on a trade route connecting Białystok and Königsberg.

[8] In June 1941, some 300 Jews were killed in a massacre carried out by the Polish inhabitants of Szczuczyn after the town was bypassed by the invading German soldiers in the beginning of Operation Barbarossa.
