"Don't Speak" is a song by American rock band No Doubt from their third studio album, Tragic Kingdom (1995). It was released as the third single from Tragic Kingdom in the United States on April 15, 1996, by Interscope Records. Lead singer Gwen Stefani and her brother Eric Stefani, former No Doubt member, wrote the song originally as a love song.

The song went through several rewrites and new versions. Gwen modified it into a breakup song about her bandmate and ex-boyfriend Tony Kanal, shortly after he ended their seven-year relationship.
