Liaodong Bay is largest and longest of the three main bays of the Bohai Sea, the innermost gulf of the Yellow Sea.
Although named after the Liaodong Peninsula, the bay is located directly south of the Liaoxi region, almost entirely west of the Liao River. It is bounded by the coastline of cities from southern Liaoning province and eastern Hebei province, between the Laotieshan Cape at Dalian's Lüshunkou District in the east, and the Daqing River estuary at Tangshan's Laoting County in the west.
The major rivers that drain into the Liaodong Bay include Luan River, Daling River, Xiaoling River, Liao River and Daliao River.
