NTS Radio (also known as NTS Live or simply NTS) is an online radio station and media platform which launched in Hackney, East London. The station was founded in April 2011 by Femi Adeyemi "for an international community of music lovers". NTS broadcasts from its studios in London and Los Angeles, as well as remote worldwide broadcasts from its mix of resident hosts and guests. NTS produces a diverse range of live radio shows, digital media and events.

The Guardian has described NTS as "redefining radio" and The New Yorker described it as a radio "which reshaped how musicians and fans around the world saw and heard one another".

In May 2020, the Financial Times reported that NTS had picked up more than 2.5 million unique monthly listeners. The same article reported that "fifty per cent of NTS's music cannot be found on Spotify [...] either because it's not available on Spotify yet or because it's a rare undiscovered gem from decades ago". GQ reported in early 2023 that NTS had 3 million unique monthly listeners and 800 resident hosts.

NTS has permanent studios in London, Manchester and Los Angeles, as well as regular remote broadcasts from around the globe. According to the Institute of Contemporary Arts, "NTS Radio is a family of like-minded and passionate individuals, dedicated to supporting exciting music and culture through online radio and events. NTS uncovers the best of the musical past, celebrates the present and cultivates the future of the underground music scene, and prides itself on being open-minded and experimental".
