斯奎尔湾是南极洲的海湾，位于葛拉汉地，宽18公里，入口处是马蹄岛，该海湾由英国探险队命名并绘入地图，现时由南极条约体系管理。

Square Bay is a bay, roughly square in outline and 10 nautical miles (18 km) wide, indenting the west coast of Graham Land between Nicholl Head and Camp Point. Most of the entrance to the bay is occupied by Horseshoe Island, which limits access to a narrow southern strait opening onto Marguerite Bay and a narrower northwestern strait opening onto the mouth of Bourgeois Fjord. Mapped and named by the British Graham Land Expedition (BGLE), 1934–37, under Rymill.
