Petachiah of Regensburg, also known as Petachiah ben Yakov, Moses Petachiah, and Petachiah of Ratisbon, was a German/Bohemian rabbi of the twelfth and early thirteenth centuries. At some point he left his place of birth, Regensburg in Bavaria, and settled in Prague. He is best known for the description he wrote to document his extensive travels during the late twelfth century throughout Eastern Europe, the Caucasus, and the Middle East. He visited places such as Poland, Russia, Syria, Armenia, and Greece. His work was later published, apparently in an abridged form, in a travelogue that eventually became known under the title Travels of Rabbi Petachia of Ratisbon.
