RadioTAB is a radio station primarily covering horse and greyhound racing in Australia and internationally, operated by Tabcorp, which operates the Totalisator Agency Boards based in Queensland, Tasmania, South Australia and Northern Territory. RadioTAB's studios are in Brisbane City.

4TAB commenced 1 January 1992. The official opening was conducted on air on 23 January 1992.

Prior to the licence being bought by the TAB, the station was known as 4IP. It commenced in 1935. Between 1965 and 1977, 4IP had a most successful hit music format in Brisbane, and was aligned with its Melbourne and Sydney cousins 3XY and 2SM. In the 1980s, FM radio started making inroads into 4IP's popularity it changed its callsign to 4IO and adopted a slogan of Radio 10, then STEREO 10 and later "Light and Easy 1008".

The station's breakfast show airs daily from 5am, providing listeners with the latest sporting news and results from a variety of sports and codes.

The station's morning shows "Racing Active" is presented from 8:30am Monday to Friday (AEST), and "Select Racing" from 7am on Saturdays and Sundays. The programs feature interviews and racing news, as well as previews of race meetings being covered on that day. It also features racing broadcasts from Australian and international venues when scheduled. Special feature or code specific segments for Harness and Greyhound racing are also featured.

The majority of RadioTAB's programming is a continuous broadcast of thoroughbred, harness and greyhound racing. This occurs daily from 11:30am. While overnight from 2am, a shared programme is taken from Sky Racing.

Following the merger of Tatts Group, which operated RadioTAB for its jurisdictions (its wagering services then styled UBET), with fellow wagering and gaming operator Tabcorp, RadioTAB is now a sister station to Sydney-based Sky Sports Radio. Both stations have retained their separate identities as of 2021.
