Pacific Northwest Wresting (PNW), also known as Portland Wrestling (PW), is the common name used to refer to different Portland, Oregon based professional wrestling companies, both past and present. The first such company was founded by Herb Owen in 1925. It became the Northwest territory of the National Wrestling Alliance from the Alliance's inception in 1947 until 1992. The area was brought to its prime by Herb's son, Don Owen, and this version of Pacific Northwest Wrestling saw many of the top names in the business come through on a regular basis and was considered one of the main territories from the 1960s to the 1980s.

Following a slowdown in the wrestling business during the early 1990s, and a declaration of bankruptcy by their television show's main sponsor (which led to their show ending production in December 1991 and being replaced by syndicated WWF programming), Pacific Northwest Wrestling, as it had been known for 67 years, was forced to close its doors in July 1992.

PNW promoter Sandy Barr purchased the company from the Owen family in 1992 and attempted to continue the tradition of professional wrestling in the Pacific Northwest under the name "Championship Wrestling USA." Finding moderate success, Barr eventually closed the company completely in 1997.

A new promotion popped up in 2000 calling itself "Portland Wrestling" and claiming to be a new version of the old Pacific Northwest/Portland Wrestling and stressing a "title linage" to the old NWA PNW Championships. Unlike the previous version of PNW/Portland Wrestling, however, the current incarnation of PW is not an NWA member. In addition, the promotion has taken on a more "extreme" style in the vein of ECW and CZW.
