WPFO (channel 23) is a television station licensed to Waterville, Maine, United States, serving the Portland area with programming from the digital multicast network Roar. It is owned by Sinclair Broadcast Group alongside CBS/Fox affiliate WGME-TV (channel 13). The two stations share studios on Northport Drive in the North Deering section of Portland; WPFO's transmitter is located on Brown Hill west of Raymond.

WPFO was built as WMPX-TV and began broadcasting in August 1999. It was Portland's Pax affiliate. In 2003, Paxson sold the station to Corporate Media Consultants Group, which converted it to a Fox affiliate that April. At the time, Portland had not had a Fox affiliate since October 2001. WGME-TV began producing a 10 p.m. newscast for WPFO in February 2007 and expanded its relationship with a morning newscast in 2010. Sinclair acquired the station's non-license assets in 2013, with Cunningham Broadcasting purchasing the license in 2017. In December 2025, WPFO's Fox subchannel moved to WGME-TV.
