Rendall (Old Norse: Rennudalr or Rennadal) is a former parish in Mainland, Orkney. It is in the north west of the island and lies east of the parishes of Birsay and Evie and north east of Harray. The island of Gairsay is also in the parish.
Rendall was later merged with Evie, and now forms part of the civil parish of Evie and Rendall.
