PacWest Center, Office skyscraper in downtown Portland, United States

PacWest Center is a glass-clad office tower in downtown Portland featuring 30 stories and a metallic exterior. The structure rises prominently along the city's financial district with its reflective surface and clean lines.

Construction of PacWest Center began in October 1982 and the tower was formally dedicated on November 1, 1984. Its name came from anchor tenant Pacific Western Bank of Oregon, whose Oregon operations KeyCorp acquired in 1986. Tokyo-based Mitsubishi Estate Co. was majority owner from the building's opening, and in 1985 the design earned Hugh Stubbins & Associates and Skidmore, Owings & Merrill the top honor award from the Portland chapter of the American Institute of Architects.

The name comes from Pacific Western Bank of Oregon, the anchor tenant when the tower opened in 1984. KeyCorp bought the bank's Oregon operations in 1986 and folded them into KeyBank, so the name outlived the tenant. Law firm Schwabe, Williamson & Wyatt has occupied space here since 1984.

The tower occupies the block bounded by Southwest Fifth and Sixth Avenues and Salmon and Main Streets, so it can be picked out from the sidewalks of the downtown transit mall. The lobby was remodeled in 2002; the upper floors are leased offices and not open to the public.

A pine tree stood on a 25th-floor balcony from the tower's construction until it died in July 2026. The building's metallic look comes from aluminum panels imported from Japan, and its concrete-steel composite frame is visually similar to the shorter Metropolitan Park towers in Seattle.
