Kerkethoueris (Koine Greek: Κερκεθοηρις), or Per-Geregentaweret in ancient Egyptian (transliteration: pr-grg-n-tꜢ-wr.t, meaning: "Established House of Taweret"), is an ancient Egyptian town in the Faiyum Oasis, governed under Nehet-Pehut, the twenty-first nome of Upper Egypt. The ancient settlement was located in the south-west of the oasis at the modern village of Izbet el-Khamsin el-Mostagedda (Arabic: عزبة الخمسين المستجدة).
