Park Avenue West Tower, Modern skyscraper in downtown Portland, Oregon, United States

Park Avenue West Tower is a 30-floor high-rise at 1050 SW Park Avenue in downtown Portland, Oregon. It rises 502 feet (153 m) and holds offices, ground-floor retail and 202 apartments on its upper 15 floors. TVA Architects designed it for TMT Development; it is the city's fourth-tallest building, after the Wells Fargo Center, KOIN Center and US Bancorp Tower.

Planned for completion in 2010 as a 33-floor tower, the project was halted in April 2009 and the bare foundation stood for over four years, nicknamed "Moyer's Ruins". Work resumed in October 2013 after redesigns cut it to 30 floors, 15 of them holding 202 apartments. It topped out in February 2015 at 502 feet and opened in February 2016, 92% occupied.

The tower's name comes from its address on SW Park Avenue. Its ground floor was planned for retail, including a NikeTown store, while Stoel Rives leased 11 floors as the main office tenant. Since opening, more than 20 of its 202 apartments have been used as short-term rentals without permits, a practice The Oregonian reported in 2018.

The building sits in Portland's main business district and is easy to reach on foot from surrounding areas. Keep in mind this is primarily an office and residential location, so public areas inside are limited compared to attractions designed for tourism.

The tower's top four floors came from a height bonus: developers added 1,650 square feet of bike facilities, including public commuter showers, bike parking and lockers, beneath the connected Director Park subsurface parking, earning a 40-to-1 bonus. The site sat as a foundation and debris for over four years, nicknamed "Moyer's Ruins".
