Hyde or Hyda was a town of ancient Cappadocia and later of Lycaonia, near the frontiers of Galatia. It became a bishopric; no longer the seat of a residential bishop, it remains, under the name Hyda in Lycaonia, a titular see of the Roman Catholic Church.
In the Hittite period, it may have been Uda.
Its site is tentatively located near Akçaà Âehir, Karaman Province, Turkey.
