Docusign Tower, previously the Wells Fargo Center, is a skyscraper in Seattle, in the U.S. state of Washington.

The exterior façade is composed of a six-sided, steel-framed tower that features a combination of tinted continuous double-glazed glass and polished spring rose granite panels. As is common with buildings in downtown Seattle, Docusign Tower rests on a slope. The eastern entrance facing Third Avenue is slightly more than two stories higher than the Western side facing Second Avenue. On the west side, the building has a public hill-climb on two flights of outdoor escalators that were encased in clear tubes until 2006 when they were updated with a simpler, yet more modern glass roof. The building has three levels of outdoor plazas.{{cn|date=November 2022}} Several retail spaces face the west plaza.{{cite web |title=999 Third Avenue Retail |url=https://www.jllproperty.com/assets/doc/999third_flyer_email_9555601.pdf |publisher=JLL |accessdate=November 1, 2022}}
