This article is about Tacoma, Washington; for other meanings, see Tacoma (disambiguation).

Tacoma (pronounced [təˈkoʊmə]) is a medium-sized port city in Pierce County in the U.S. state of Washington. The city is located at the southern end of Puget Sound, about 51 km southwest of Seattle, 50 km northeast of the state capital, Olympia, and about 93 km northwest of Mount Rainier National Park. Tacoma is part of the Seattle-Tacoma-Bellevue Metropolitan Statistical Area, which had a population of about 3.8 million in 2016, according to the U.S. Census Bureau's official estimate.

Seattle/Tacoma International Airport (Sea-Tac) (IATA airport code SEA) is located approximately 35 km away to the north. SeaTac is now a city in its own right. It was named after the cities of Seattle and Tacoma, which use the airport. Tacoma is also the seat of Pierce County government.

The population was 198,397 on April 1, 2010, making Tacoma the second largest city on Puget Sound after Seattle and the third largest city in the state after Seattle and Spokane. The residents call themselves Tacomans. Mount Rainier (an active stratovolcano of the Cascade Mountains), called Mount Tahoma (from the Puyallup word "tacobet" for mother of water) by the region's Native Americans, is the namesake of the city, which is also known by the nickname "City of Destiny". Tacoma received this epithet when the city was designated as the western terminus of the Northern Pacific Railroad. Tacoma's choice was decidedly influenced by its proximity to Commencement Bay in Puget Sound. The connection of maritime traffic to the railroad made Tacoma's motto: "Where rails meet sails". Today, the Port of Tacoma (Port of Tacoma) is still very important, both for the region and for the entire USA and the Pacific region. The port is the sixth largest container port in North America, handling 17 million tons, making it one of the region's major employers (2004: 43,138 direct and indirect jobs). The main goods shipped are cars (mainly from Japan and Korea), construction vehicles, tractors and grain.

The Tacoma Narrows Bridge, one of the longest suspension bridges in the world, connects Tacoma to the Kitsap Peninsula via Highway 16. The city government invested large sums in the renewal of the city center at the beginning of the 21st century. Among other things, a campus for a branch of the University of Washington was built, a modern electric streetcar (Tacoma Link) was installed and various museums were built or renovated. The "Thea Foss Waterway", a small bay, was lavishly restored and houses, among other things, a marina.

Tacoma has been named one of the most livable cities in the country. It has also been named one of the most walkable cities in America. A 2004 study, on the other hand, concluded that Tacoma was the most stressful city when combining the criteria of unemployment, divorce rate, commute times, suicide rate, crime rate, poor mental health, alcohol abuse, and the number of cloudy days (among the 30 cities studied).
