Yevpatoria Bay (Russian: Евпаторийская бухта, Ukrainian: Євпаторійська бухта, Crimean Tatar: Kezlev körfezi, Кезлев корьфези) is a bay in the Black Sea near Yevpatoria, Crimea.

[2] It forms an arm of the Gulf of Kalamita.

The bay is situated on a geological fault between the Alma Syncline and the Tarkhankut rise.

Tectonic movements have formed various depositions within the bay and indicate a relative sea level increase of approximately 2 metres since the 1st millennium BCE.

With regard to shipping it is relatively shallow and exposed.
