"Don't Speak" is a song by American rock band No Doubt from their third studio albumTragic 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.
"Don't Speak" was written by lead singer Gwen Stefani and her brother Eric Stefani, and produced by Matthew Wilder. Originally a love song, Stefani rewrote the lyrics almost completely after her breakup with the band's bass player Tony Kanal. According to her, "It used to be more upbeat, more of a Seventies rock-type thing. [When] Tony and I broke up... it turned into a sad song."  A live version that exists from April 1994 shows off a bouncy tune that has the same skeleton as the released version, but not the same urgency. The band performed part of the original song on VH1 Storytellers on August 10, 2000.
The band's lead guitarist Tom Dumont said about the song's composition:
There's a lot of stories about that song, because that one unfolded over a longer period of time. Originally, Gwen's brother wrote most of that song, and then after we got at it as a band, Gwen changed the lyrics around to fit her life. Musically, we brought it to another level, but near the end we reworded it. There's an earlier version of the song where the verses are totally different, which is a really beautiful version and it's awesome but it's way more jazzy and really different. That song had a long incubation process.
"Don't Speak" is composed in the key of C minor and F minor. A demo version also appeared on a demo CD, which was presented to Interscope Records prior to the release of Tragic Kingdom.
Upon release, "Don't Speak" immediately began to receive extensive airplay and it eventually became the most widely played song on American radio in 1996. It reached number one on Billboard's Hot 100 Airplay chart and maintained that position for 16 non-consecutive weeks, a record at the time. Although the record would be broken in 1998 by the Goo Goo Dolls's single "Iris" with 18 weeks at number one, the song remains in second place of songs with the most weeks at number one on the Hot 100 Airplay. For all its airplay though, "Don't Speak" was not allowed to chart on the Billboard Hot 100 as no commercial single was released for it in the United States (a requirement for charting purposes at the time). Slate magazine music critic Chris Molanphy has stated that if the song had been eligible to chart, it almost certainly would have claimed the number one spot.
"Don't Speak" also stayed at number two on Alternative Airplay chart for five consecutive weeks, blocked by the band Bush's single "Swallowed". The song also proved to be a crossover hit, reaching number one on the Adult Top 40 chart for 15 consecutive weeks as well as numbers six and nine on the Adult Contemporary and Rhythmic charts, respectively. It was ultimately placed at number one on the Hot 100 Airplay year-end chart of 1997.
Internationally, "Don't Speak" was also very successful. In February 1997, it peaked at number one in both the United Kingdom and Ireland for three weeks. Elsewhere in Europe, "Don't Speak" reached the top position in Belgium, the Netherlands, Norway, Sweden and Switzerland. Australia was another major music market where the song received widespread airplay, debuting at number one and maintaining the peak position for eight weeks.
Before the music starts, at the beginning of the music video, there is a scene of Kanal picking a rotten orange from a tree (these scenes are usually cut out when VH1 airs this video). The majority of the video for "Don't Speak" takes place on Stage 2 at Mack Sennett Studios in Silver Lake as the band plays. Other scenes tell the story of how the media mainly focused on Stefani while the band was always in the background. The second half of the video features snippets of live footage filmed during the band's performance with Dog Eat Dog and Goldfinger at the Roseland Ballroom in New York City on August 21, 1996. The video also features a short footage showing Dumont playing together with Foo Fighters's guitarist Pat Smear. The video ends with Kanal replacing the orange in the tree, which is actually footage of Kanal in reverse pulling the orange off.
Tensions in the band had been running high and they reportedly were on the verge of breaking up the day before they were scheduled to film the video. They decided to go ahead and film it as a form of "therapy".
