Westlake Center, Shopping center and high-rise building in downtown Seattle, United States

Westlake Center is a four-story mall and a 25-story office tower called Westlake Tower, between 4th and 5th Avenues across Pine Street from Westlake Park in downtown Seattle. The mall's third floor holds the Seattle Center Monorail terminus, and the second floor has the Bites on Pine food hall. A flagship Zara is among the remaining stores.

The original Westlake Center opened on March 24, 1962, as an open pedestrian mall and southern terminus of the Seattle Center Monorail, designed by Adrian Wilson and Associates. In 1981 the Washington State Supreme Court ruled a redevelopment plan unconstitutional because the city used eminent domain for a private retail mall. The current complex, designed by RTKL Associates, opened on October 20, 1988.

Westlake Park across Pine Street is regarded as Seattle's town square, and political figures and celebrities have given speeches from the center's balcony. The mall hosts Seattle's version of the Macy's Thanksgiving Day Parade, and in 1999 WTO Ministerial Conference protests saw stores vandalized; Occupy Seattle also camped here.

The location is easily accessible by monorail, light rail, and bus, with direct connections to all three transit options at the site. Multiple entrances allow visitors to enter from different directions and the building remains open during standard business hours.

The building serves as a rare example of seamless integration between public transit and shopping, allowing visitors to step directly from trains and buses into the retail spaces without going outside. This direct connection makes it an important hub in the city's transportation network.
