Obbe Philips (ca. 1500–1568) (also spelled Philipsz and Filips) was one of the early founders of Dutch Anabaptism. He was the illegitimate son of a Roman Catholic priest from Leeuwarden. Philips studied medicine, and became a barber and a surgeon. He married in 1530 and set up his business in Leeuwarden. The Anabaptists who would become known as Mennonites were originally called Obbenites or Obbenists. W. J. Kühler, in Geschiedenis I (1932), concluded that "in Obbe the brotherhood certainly lost its most appealing leader."
