Kiss is a British digital radio station owned and operated by Bauer Media Audio UK as part of the Kiss Network. Kiss broadcasts nationally to the UK via DAB digital radio, as well as on Bauer's Rayo platform.

The station started in 1985 as a pirate radio station, Kiss FM, before becoming the UK's first legal black and dance music specialist radio station in 1990 as Kiss 100, broadcasting in London on 100.0 FM. Kiss became a digital-only station in 2024 when its FM frequencies in London, Norfolk and the west of England were taken over by Hits Radio.

According to RAJAR, the station broadcasts to a weekly audience of 1.283 million as of October 2025.

Kiss FM first broadcast 7 October 1985 as a pirate radio station, initially to South London then across the whole city, on 94FM. Kiss FM was founded by Gordon "Mac" McNamee, George Power (of London Greek Radio), and Tosca Jackson, with its engineer Pyers Easton. Transmitting seven-days from the start, it would be regularly taken off-air by the authorities and so became a weekend operation shortly afterwards.

The station developed a cult and committed following across Greater London, with figures in the press at the time stating that the station commanded some 500,000 listeners while operating as an unlicensed pirate station, and an Evening Standard readers' poll in 1987 put Kiss second, behind Capital Radio. Gordon Mac approached a successful London club promoter, Guy Wingate, to discuss ways of improving the Kiss FM profile. As a result, Wingate launched the very successful Kiss nights at the Wag Club (which included the first ever UK acid house party – an idea put forward by Colin Faver and Danny Rampling, both DJs on the station). These nights increased the station's credibility with its target audience and Wingate joined the Kiss team, followed shortly thereafter by Lindsay Wesker. Kiss would also run its own night at Dingwalls and adopted the slogan Radical Radio.

Mac and ten of the DJs on the station including Norman Jay, Jonathan More, Colin Faver, Trevor Nelson, and Tim Westwood would become "shareholders" in a company called Goodfoot Promotions, with Mac heading up the station as its majority holder. By 1988, Kiss was at its strongest with a DJ line-up which had become the cream of London's clubland, and in that December, Mac and the other shareholders would announce that they would decide to close down in order to apply for a legal licence. This was in response to the UK Government and Independent Broadcasting Authority (IBA) announcement that twenty new "incremental radio" licences would be advertised, including one for London. Stations were told that they would have to voluntarily closedown when applying, and so on New Year's Eve 1988, the final broadcast went out with an outside broadcast at Dingwalls.

Kiss would submit a strong application with widespread support from listeners, clubs, record labels and music magazines, however on 12 July 1989, the IBA instead awarded the licence to Jazz FM.

Despite the temptation to return to the air again illegally, Kiss held off as the IBA had said they would make more licences available, which they did in September 1989. Kiss re-prepared their application, but this time got the backing and majority investment of media group EMAP. On 17 December 1989, the IBA announced that Kiss had been awarded a licence on their second attempt.
