Bátaszék (German: Badeseck, Serbian: Батсек, romanized: Batsek) is a town in Tolna County, Hungary.

To defend against attacks from barbarians, the Romans constructed fortifications called Pannonian Limes, which formed a continuously manned defensive line stretching from Óbuda to Osijek.

Following the collapse of the Roman Empire, Bátaszék experienced waves of migration from various ethnic groups, including Sarmatians, Huns, Avars, Franks, Slavs, and eventually Magyars.

Due to its resistance to Turkish conquest, Ottoman Grand Vizier Pargalı Ibrahim Pasha had the town razed to the ground in 1529.

These newly arrived Germans were industrious tinsmiths, wheelwrights, weavers, and cobblers, who developed the rural area into a bustling market economy.

During Second World War, Bátaszék was captured on 28 November 1944 by Red Army troops of the 3rd Ukrainian Front in the course of the Budapest Offensive.

Shortly after, the mass deportation of German-Hungarians began, and over 4000 German townsfolk were forced from their homes, and replaced with Hungarians from Transylvania and Slovakia.
