24/7 Trauma & Biohazard Cleanup Near West Algona Algona, WA

Algona is a small city in King County, Washington, surrounded by Auburn to the north and east, the city of Pacific directly to the south, and unincorporated King County to the west.

The first homesteaders arrived in the Algona area in the 1870s, and growth followed the completion of the Seattle-Tacoma Interurban Railway in 1902.

Developer C. D. Hillman platted the townsite in 1906 as Valley City, but postal officials rejected that name, and the replacement name 'Algoma' — said to mean 'Valley of Flowers' — was recorded as 'Algona' by a postal clerical error that was never corrected.

Algona's post office was established in 1909, and the community officially incorporated as a city on August 22, 1955.

The 2020 census counted 3,290 people in Algona, up from 3,014 people in 953 households at the 2010 census.

A 2024 American Community Survey estimate put Algona at roughly 930 households averaging about 3.5 persons per household.

Algona is known for its wetlands and the great blue herons that frequent them — the blue heron serves as the city's logo.

The city covers only about 1.3 square miles of valley floor in the Green River valley area of south King County.

Algona's children attend schools in the Auburn School District, whose schools serve the small city from neighboring Auburn.
