University of Washington, founded in 1861, is a public research university in Seattle, Washington, United States. UW is the largest university in the northwestern United States and one of the oldest public universities on the west coast. The university has three campuses, with its flagship campus in Seattle's University District and much smaller branch campuses in Tacoma and Bothell. Its operating budget for fiscal year 2005 was $3.1 billion. The university is also considered a Public Ivy.

In 2008, the school placed 16th in the world's top universities, according to the Academic Ranking of World Universities.

The city of Seattle was one of several settlements in the mid to late 19th century vying for primacy in the newly formed Washington Territory. In 1854, territorial governor Isaac Stevens recommended the establishment of a university in Washington. Several prominent Seattle-area residents, chief among them Methodist preacher Daniel Bagley, saw the siting of this University as a chance to add to the city's prestige. They were able to convince early founder of Seattle and member of the territorial legislature Arthur A. Denny of the importance of Seattle winning the school. The legislature initially chartered two universities, one in Seattle and one in Lewis County, but later repealed its decision in favor of a single university in Lewis County, provided locally donated land could be found. When no site emerged, the legislature, encouraged by Denny, relocated the university to Seattle in 1858.
