施拉赤塔（波兰语：Szlachta）是指波兰王国、立陶宛大公国（他们在1569年合并为波兰立陶宛联邦）和在他们的影响下逐渐波兰化的地方(如普鲁士公国和罗塞尼亚)等地的贵族。

The szlachta ([ˈʂlaxta], exonym: Nobility) was a legally privileged noble class with origins in the Kingdom of Poland. It gained considerable institutional privileges between 1333 and 1370 during the reign of King Casimir III the Great. In 1413, following a series of tentative personal unions between the Grand Duchy of Lithuania and the Crown Kingdom of Poland, the existing Lithuanian nobility formally joined this class. As the Polish-Lithuanian Commonwealth (1569–1795) evolved and expanded in territory, its membership grew to include the leaders of Ducal Prussia, Podolian and Ruthenian lands.
