One Main Place is a privately owned commercial office building in Downtown Portland, in the U.S. state of Oregon.

The structure was designed by architectural firm Skidmore, Owings and Merrill and built by Hoffman Construction Company, with completion coming in 1982.

[2][3] The pension fund for Los Angeles' police and fire departments bought the office tower in December 1998 for $44.5 million, after having owned 10 percent of the building since the 1995 sale.

[4] RREEF had attempted to sell the office tower in 2009, but halted efforts in October after bids were lower than anticipated.

The project management team was James Drinkward of Sterling-Pacific, Paul Amos of Harper Winn, and Chuck Marvin of RSI Results.
