The Princely Abbey of Kempten was an ecclesiastical principality of the Holy Roman Empire for centuries until it was annexed to the Electorate of Bavaria in the course of the German mediatization in 1803.

Kempten is the largest town of Allgäu, in Swabia, Bavaria, Germany. The population was about 68,000 in 2016. The area was possibly settled originally by Celts, but was later taken over by the Romans, who called the town Cambodunum. Kempten is the oldest urban settlement (town) in Germany.
