Downtown is the central business district of Seattle, Washington. It is fairly compact compared with other city centers on the U.S. West Coast due to its geographical situation, being hemmed in on the north and east by hills, on the west by Elliott Bay, and on the south by reclaimed land that was once tidal flats. It is bounded on the north by Denny Way, beyond which are Lower Queen Anne, Seattle Center, and South Lake Union; on the east by Interstate 5, beyond which is Capitol Hill to the northeast and Central District to the east; on the south by S Dearborn Street, beyond which is Sodo; and on the west by Elliott Bay, a part of Puget Sound.

Elliott Bay is a part of the Central Basin region of Puget Sound. It is in the U.S. state of Washington, extending southeastward between West Point in the north and Alki Point in the south. Seattle was founded on this body of water in the 1850s and has since grown to encompass it completely. The waterway it provides to the Pacific Ocean has served as a key element of the city's economy, enabling the Port of Seattle to become one of the busiest ports in the United States.
