Interbay is a neighborhood in Seattle, Washington in the United States consisting of the valley between Queen Anne Hill on the east and Magnolia on the west, plus filled-in areas of Smith Cove and Salmon Bay. The neighborhood is bounded on the north by Salmon Bay, part of the Lake Washington Ship Canal, across which is Ballard; on the south by what remains of Smith Cove, an inlet of Elliott Bay; on the east by 15th Avenue W. and Elliott Avenue W.; and on the west by Thorndyke, 20th, and Gilman Avenues W. The Ballard Bridge crosses the ship canal from Interbay to Ballard.

Much of Interbay is taken up by BNSF Railway's Balmer Yard. Interbay is also home to Fishermen's Terminal on Salmon Bay and the Port of Seattle's Piers 86, 90, and 91 on Smith Cove. Its main thoroughfares are Elliott Avenue W. (northwest- and southeast-bound) and 15th Avenue W. (north- and southbound).

It appears that the valley between Magnolia and Queen Anne was carved out during the Vashon Stade of the Fraser glaciation (roughly 14,000–17,000 years ago), A thin layer of sand throughout the area may date from a tsunami following an earthquake along the Seattle Fault Zone about 1,000 years ago.

Although Interbay fell within the traditional geographic range of the Duwamish, early ethnographers did not record contact-era or earlier Native American villages in the area. Nonetheless, University of Washington ethnologist T. T. Waterman lists several native place names at or near Smith Cove and Salmon Bay.
