"Secret Smile" is a song by American rock band Semisonic.

The single, released to American radio on January 11, 1999, gained the band brief international popularity.

A live version of the song recorded at The Gorge Amphitheatre, as well as a mix by the Orb had previously been released as a B-side to "Singing in My Sleep".

The song was featured in the film Simply Irresistible and in the TV series Charmed and Dawson's Creek.

Songwriter Dan Wilson has said that the melody for the song came to him in a dream, and he woke up in the middle of the night, rushed to a piano, and wrote it down.
