"I'm Yours" is a song written and recorded by American singer-songwriter Jason Mraz, released in 2008 as the first single from his third studio album We Sing.

The song was originally released on a limited edition EP called Extra Credit as a demo in 2005 to promote his second studio album Mr. A–Z.

[12] Mraz first launched the song from the La Costa Resort and Spa in Carlsbad, California, at Michele Clark's Sunset Sessions in 2008.

[13] Sheet music for the song "I'm Yours" shows the key of C major with a moderate tempo of 70 beats per minute, and a chord progression of B-F#-G♯m-E.[14] Throughout 2008, "I'm Yours" slowly increased in airplay and digital sales and would go on to become Mraz's biggest hit to date, charting higher than his previous pop hit, 2003's "The Remedy (I Won't Worry)".

A year into its release, it topped another chart for the first time, when it hit number one on the Billboard Hot Adult Contemporary Tracks during the week of February 5, 2009.

[16] Despite weak initial download sales, it became the eighth best-selling digital song in the United States by January 2012.

[18] It is Mraz's most successful global single to date, reaching number one in Sweden and Norway, and the top ten in Canada, United States, Austria, Australia, Germany, Switzerland, Spain and Italy.

[22] After gazing thoughtfully into a fish tank and putting on a backpack, Mraz's video self departs an apartment, leaving the unit's key behind.

Doane hunkered down next to the big city of couple of guys in a pick-up truck who take him to the little-known skateboard park on Oahu's North Shore.

The waterfall, on Oahu's windward side, was suggested by the girl he's seen conversing with at the skate park—a North Shore resident he and Doane had just met.

[22] After a plane ride from Oahu, Mraz catches a shuttle at the Lihue Airport and winds up in the east-side Kauai town, which he simply explores on foot.
