KTNW (channel 31) is a PBS member television station in Richland, Washington, United States, serving the Tri-Cities area. The station is owned by Washington State University (WSU) and is part of its Northwest Public Broadcasting group of radio and television services. KTNW's studios are located on the first floor of the West Building on the WSU Tri-Cities campus on Crimson Way in Richland, and its transmitter is located on Jump Off Joe Butte. Master control and most internal operations are based at the studios of former sister station KWSU-TV (channel 10) in the Murrow Communications Center on WSU's main campus in Pullman.
WSU has broadcast public television to the Tri-Cities since 1968, though it was not until 1987 that a full-power station was erected to serve the region.
The station serves the eastern portion of the Yakima–Tri-Cities market; the western portion is served by KYVE in Yakima, a satellite of KCTS-TV in Seattle. It is carried on the Yakima–Tri-Cities DirecTV and Dish Network feeds, and operates a translator on UHF channel 33 in Pullman.
