"Don't Speak" is a song by the American rock band No Doubt. It was released as the third single from the band's second album Tragic Kingdom (1995) in 1996.

Despite the song's popularity, "Don't Speak" did not chart on the Billboard Hot 100 (as rules of the times required commercial singles for charting and one was not issued for the song), but it did reach number one on the Billboard Hot 100 Airplay and stayed for sixteen weeks. The song also reached number one in the UK, New Zealand, Netherlands, and Australia. The single is No Doubt's most successful international single, propelling them to superstardom. "Don't Speak" is arguably No Doubt's biggest hit and was nominated for the Song of the Year and Best Pop Performance By A Duo Or Group With Vocal at the Grammy Awards of 1998.

The song was ranked at number 495 in Blender magazine's "The 500 Greatest Songs Since You Were Born".
