普吉特海湾（英语：Puget Sound；英语发音：/ˈpjuːdʒɪt/）是一个位于美国西雅图西岸峡湾，北临加拿大温哥华岛，属萨利希海的一部份。海湾本身是一个河口系统，结构复杂，交织着通往海洋的水道和盆地。当中有一大一小的信道透过胡安·德富卡海峡与太平洋相连，较大的为阿德默勒尔蒂湾（Admiralty Inlet），较小的是迷幻水道（Deception Pass）。通过阿德默勒尔蒂湾的海水，占海湾与胡安·德富卡海峡之间的潮汐水体交换的2%。海湾的范围，从北起迷幻水道起计算，到南方的奥林匹亚，距离约160公里，平均海深约60公尺，最深处是基沙普县的Indianola与Kingston之间的Point Jefferson对出海底，深度有280公尺。而海湾的主要盆地位于惠德比岛南端与塔科马之间，水深180公尺。

Puget Sound /ˈpjuːdʒɪt/ is a sound along the northwestern coast of the U.S. state of Washington, an inlet of the Pacific Ocean, and part of the Salish Sea. It is a complex estuarine system of interconnected marine waterways and basins, with one major and two minor connections to the open Pacific Ocean via the Strait of Juan de Fuca—Admiralty Inlet being the major connection and Deception Pass and Swinomish Channel being the minor. Flow through Deception Pass is approximately equal to 2% of the total tidal exchange between Puget Sound and the Strait of Juan de Fuca. Puget Sound extends approximately 100 miles (160 km) from Deception Pass in the north to Olympia, Washington in the south. Its average depth is 450 feet (140 m) and its maximum depth, off Point Jefferson between Indianola and Kingston, is 930 feet (280 m). The depth of the main basin, between the southern tip of Whidbey Island and Tacoma, Washington, is approximately 600 feet (180 m).
