"Keep This Fire Burning" is a song by Swedish pop singer Robyn, released as the first single from her third album Don't Stop the Music. It was released in Sweden on September 21, 2002, where it became her highest charting single since 1995's "Do You Really Want Me (Show Respect)". The song was also released as a single in Australia under the name "By Your Side", due to the Australian bush fires which were happening at the time. In 2008, a re-recorded version of the song appeared on the special edition of Robyn's eponymous album.

Robyn did not release "Keep This Fire Burning" in the United Kingdom, leading British soul singer Beverley Knight to cover it.

British soul singer Beverley Knight released "Keep This Fire Burning" as the third and final single from her fourth studio album, Affirmation. Included on the CD single release were mixes from Stargate (which sampled a portion of Robyn's original vocals) and Full Phat (featuring a rap from Estelle).

"Keep This Fire Burning" was a massive airplay hit for Knight, peaking inside the UK airplay top 5. The single became her 6th Top 20 and 12th Top 40 solo single in the UK, reaching #16.

In 2008, British dance act Outsiders released a dance cover of the song with vocals by Amanda Wilson. The track was then remixed by Wawa and then again by Freemasons, who also collaborated with Wilson on various tracks such as "Watchin'". This version peaked at #80 in the UK.
