"Only Time" is a song by the Irish singer, songwriter and musician Enya, released in November 2000 as the lead single to her fifth studio album, A Day Without Rain (2000).

In 2001, "Only Time" was released again as a remix. The track was remixed by the Swiss American Federation (S.A.F.) (Christian B. and Marc Dold) with a final remix by Enya's producer, Nicky Ryan. Enya donated the earnings from the sale of that single to the Uniform Firefighters Association's Widows' and Children's Fund to help the families of fire fighters in the aftermath of 9/11. The song was also featured in the soundtrack of the motion picture Sweet November. Following the September 2001 attacks, sales of the album and its lead single, "Only Time", skyrocketed after it was used by several radio and television networks in their coverage and aftermath of the attacks. As a result, "Only Time" climbed to number ten on the Billboard Hot 100 singles chart and number one on the adult contemporary chart.

During the summer of 2001, NBC used the song in commercials to promote Friends, which ended its season on a cliffhanger. The exposure helped the song gain familiarity and increased radio play. As a result, the song became Enya's first top 40 radio hit in 12 years. The song appeared twice on the TV show Viva La Bam where it first appeared in the montage of Bam Margera destroying Don Vito's cars in "Bamiature Golf" and again in "Where's Vito?" during a retrospective for Bam's Hummer after it was thrown off the cliff by Vito. Enya performed the song at the 2001 World Music Awards. On November 13, 2013, a Volvo Trucks campaign featuring the song and Jean-Claude Van Damme was launched. The success of the ad caused "Only Time" to re-enter the Billboard Hot 100 at #43, and the UK Singles Chart at #95. The song's music video, which shows Enya performing the song in a spring, summer, fall and winter theme, was directed by Graham Fink and was released in 2000. In 2002, the song received a ECHO Award for Best Single of the Year.
