Tukwila (/tʌkˈwɪlə/ tuk-WIL-ə)[7] is a suburban city in King County, Washington, United States, located immediately to the south of Seattle.

[5] A large commercial center draws workers and consumers to the city daily; industry thrives with the confluence of rivers, freeways, railroads, and Seattle–Tacoma International Airport.

The Duwamish lived in cedar longhouses, hunted and fished, picked wild berries, and used the river for trade with neighboring peoples.

Foster would become known as the "Father of Tukwila" and represented King County in the Washington Territorial Assembly for 22 years.

Today, the site of Foster's home on the banks of the Duwamish River is part of Fort Dent Park, which also served as a military base during the Indian Wars of the 1850s.

In the early years, the small village grew into an agricultural center and remained a trading point in the upper Duwamish River Valley.

Early electric trains traveled along Interurban Avenue in Tukwila, connecting to Renton and a line to Tacoma.

The Interurban Railroad operated a commuter line from 1902 to 1928, making it possible to travel from Seattle to Tacoma in less than an hour.

With the main goal of establishing better fire protection and water service, better access to schools and safer roads, Tukwila was incorporated as a fourth-class city on June 14, 1908, with a population of around 450.

[11] The original city limits consisted of a single square mile centered around the local interurban depot; Riverton and Foster would be annexed later.

[14] Tukwila is located in western King County, south of Seattle and between the cities of SeaTac to the west and Renton to the east.

Of these, the violent crimes consisted of 2 murders, 24 forcible rapes, 140 robberies and 58 aggravated assaults, while 324 burglaries, 2,764 larceny-thefts, 913 motor vehicle thefts and 2 acts of arson defined the property offenses.

[26] Tukwila's location at the confluence of rivers, freeways and railroads has made it an important center of commerce.

Tukwila is also the location of corporate datacenters, including those of Microsoft, Internap, the University of Washington, Savvis, AboveNet,[27] digital.forest, HopOne, and Fortress Colocation.

[28] In 2021, Seagle Properties announced sales for the Prato District, a 320-acre (130 ha) mixed-use office, manufacturing, and retail area south of Southcenter.

Preparations for the development, which began in 2009 as Tukwila South, included an extension of Southcenter Parkway built by the city government in 2012.

[32] The Seattle Seawolves, two-time champions of Major League Rugby, had played their home games at the Starfire Sports complex since 2018.

[36] The complex also served as the administrative and training home of the Seattle Sounders FC, and the main ground of their affiliate the Tacoma Defiance, until their move to Longacres in 2024.
