"I'm So Happy I Can't Stop Crying" is a song written and recorded by English rock singer Sting. It was released from his 1996 album Mercury Falling. The song was also released as a single, and reached number 94 and number 54 on the U.S. and UK singles charts, respectively. Sting also recorded the song as a duet with country music artist Toby Keith on Keith's 1997 Dream Walkin' album. This version reached number 2 on the US Hot Country Songs charts and number 84 on the U.S. Billboard Hot 100 charts, and gave Sting his only country hit.

Sting started composing the song as a rock song, but the lyrical content pushed the song in a country direction, and it evolved into a country-rock shuffle. The song begins in the key of E-flat major, before modulating a semitone upward to E major in the final verse. Its lyrics concern a father whose wife has left him for another man and taken their two children. After a cynical beginning, he has a revelation about the connectedness of life and the universe, and finishes the song truly "so happy he can't stop crying." The music video for the song was directed by Lol Creme. During the Mercury Falling tour, Sting would often invite audience members up onto stage to sing the song along with him.
