Alibey Lagoon (Ukrainian: Алібей, Romanian: Limanul Alibei, Turkish: Alibey Gölü) is a salty lagoon (liman) on the Black Sea coast of Bilhorod-Dnistrovskyi Raion of Odesa Oblast, Ukraine. The lagoon is originated from the old mouth of the Khadzhyder River. The length of the lagoon is 15 km, width 11 km, area 72 km2. The depth is 2.5 m.
