KHBS, virtual channel 40 (UHF digital channel 21), is an ABC-affiliated television station licensed to Fort Smith, Arkansas, United States. The station is owned by Media General. KHBS' studios are located on Ajax Avenue in Rogers, with a secondary studio and news bureau on North Albert Pike Avenue/North 42nd Street (south of Kelley Highway) in Fort Smith; its transmitter is located on Cavanal Hill in northwestern Le Flore County, Oklahoma (northwest of Poteau).

The station's brand name, "40/29", comes from KHBS and satellite station KHOG-TV (virtual channel 29, UHF digital channel 15) in Fayetteville, which relays KHBS' programming to areas of far northwestern Arkansas and southwestern Missouri that are not covered by the primary station's signal. (The broad coverage area of the Fort Smith–Fayetteville DMA precludes stations with transmitters closer to Fort Smith from reaching northern portions of the market). KHOG-TV's transmitter is located near Ed Edwards Road (southeast of the Fayetteville city limits) in rural northeastern Washington County.

On cable, KHBS/KHOG is available on Cox Communications channel 7 in Fort Smith and Fayetteville.
