WHIO (1290 AM, "AM 1290 and News 95.7 WHIO") is a commercial radio station in Dayton, Ohio. It simulcasts a talk format with WHIO-FM (95.7). They are owned by Cox Media Group. The studios are at the Cox Media Center on South Main Street (Ohio State Route 48) in Dayton.

WHIO's transmitter is sited on East David Road in Kettering.

The original call letters and origin of the station was WLBW in Oil City Pennsylvania. To create a new radio service in Dayton, Cox had to purchase WLBW in Oil City, from the Petroleum Telephone Company. Cox shut down the Pennsylvania operation and moved the radio station to Dayton.

WHIO was Cox Radio's first station started by company founder Ohio Governor James M. Cox. It signed on the air on February 9, 1935. The original studios were in the Dayton Daily News building downtown, on Ludlow Street.

The station first broadcast with a power of 1,000 watts on 1260 kHz, which had been the frequency of WLBW. With the enactment of the North American Regional Broadcasting Agreement (NARBA) in 1941, WHIO moved to its current frequency at 1290 kHz. When NARBA went into effect, 90% of all AM stations in America were forced to change frequencies.

At its founding, WHIO was an NBC Red Network affiliate, also taking some shows from the NBC Blue Network. In the 1940s, WHIO switched to the CBS Radio Network. Then, as network programming moved from radio to television, WHIO switched to a full service, middle of the road format of popular music, news and sports.

In 1946, Cox Radio added an FM station, 99.1 WHIO-FM. At first, WHIO-FM simulcast the AM station. But in the 1960s, it began airing a beautiful music format. And in 1989, it became WHKO with a country music format.

In 1949, Cox added a TV station, WHIO-TV on Channel 13 (later on Channel 7). Because WHIO had been a CBS Radio affiliate, WHIO-TV also began airing CBS television programs. WHIO-TV, along with WHIO 1290 and WHKO 99.1, have been owned by Cox since their founding.
