Elliott Bay is Seattle's body of water. It is located between West Seattle and the rest of the city lying below West Point and Alki Point where it branches away from Puget Sound. The bay serves as the waterfront and Port of Seattle's home.
- On May 17, 1838, George Sinclair on a survey of Puget Sound came to Elliott Bay. He named the bay after one of the three people named Elliott on his ship, the Porpoise.
- In 1852 Arthur Denny chose the present day downtown for the site of a new settlement after sounding the bay and seeing it was adequate for a port.
