The Saint Lawrence Bay (Russian: Залив Лаврентия; Zaliv Lavrentiya) is a bay in the Bering Sea on the eastern coast of the Chukotka Peninsula, Russian Federation.

This bay is located very close to the Bering Strait, which lies only a few km to the NE.

On the southern shore of the bay at Cape Hargilah is the village of Port Lawrence.

British Captain James Cook landed for a few hours in St. Lawrence Bay and met some of the local Chukchi people in August 1778, but he didn't linger in the bay.
