San Pablo Bay is a shallow tidal estuary that forms the northern extension of San Francisco Bay in northern California in the United States. It receives the waters of the Sacramento and San Joaquin rivers, via Suisun Bay and the Carquinez Strait on its east end, and it connects to San Francisco Bay on its south end. The bay is heavily silted from the contributions of the two rivers, which themselves drain most of the Central Valley of California. The bay also receives the waters of the Napa River, which flows into the Carquinez Strait via the Mare Island Strait near its entrance into the bay.

The undeveloped portions of the periphery of the bay are plentiful with salt marshes and mudflats. The bay is a primary wintering stop for canvasback population on the Pacific Flyway, as well as a migratory staging ground for numerous species of waterfowl. Much of the northern shore of the bay is protected as part of the San Pablo Bay National Wildlife Refuge.
