达沃湾（Davao Gulf），是菲律宾南部棉兰老岛东南海岸的一个海湾，位于菲律宾海和西里伯斯海之间，面积约4，800平方公里。

达沃湾因沿岸最大港口达沃而得名，湾中最大岛屿为萨马尔岛。近年来菲律宾政府计划将达沃发展为IT中心，故此又有硅湾之称。

Davao Gulf is a gulf situated in the southeastern portion of Mindanao in the Philippines. It has an area of 308,000 hectares. Davao Gulf cuts into the island of Mindanao from Philippine Sea. It is surrounded by all five provinces in the Davao Region. The largest island in the gulf is Samal Island. Davao City, on the gulf's west coast, is the largest and busiest port on the gulf. The Bagobo, a tribe known in Davao, are living in the Davao Gulf. With the thrust of Davao City towards Information Technology and IT-Enabled Services (ITES), Davao City and the Davao Gulf area have also earned the moniker Silicon Gulf.
