"Dynamite" is a song by English recording artist Taio Cruz for the international version of his second studio album, Rokstarr (2010). Cruz co-wrote the song, along with Max Martin, Bonnie McKee, Benny Blanco, and Dr. Luke; the latter two are also the producers. It was released internationally as the fourth single from Rokstarr. In the UK, the song was released as the first single from Cruz's compilation album, The Rokstarr Collection (2010). On 30 May 2010, it was released to US and Canadian radio stations as his second single and across Europe as his fourth single. An official remix was released featuring new label mate, Jennifer Lopez.

"Dynamite" became Cruz's second number-one single on the UK Singles Chart and the Canadian Hot 100 as well topping charts in Belgium, Ireland, Australia and New Zealand. The song reached number two on the US Billboard Hot 100, and by January 2012 it had sold over 5.7 million copies in the U.S. and Canada, becoming the second best-selling song by a British artist in the digital era there, behind Adele's "Rolling in the Deep".

It was featured in the 2011 live action/CGI film Hop. It is also featured on Just Dance 3. This was played at the end of Mcctc's Trash Bash 2011.

The song "Dynamite" is written in the key of C# minor, with a tempo of 116 beats per minute. According to Cruz, "The song 'Dynamite' itself is about when you go to the club and when you go to a party and when you're just going out... you got to feel like, 'I'm just gonna explode.'"Dr. Luke and Max Martin had written the melody, and asked Bonnie McKee to write lyrics. McKee only met Cruz months after the song's release, and later said that “I thought ["Dynamite"] was the dumbest song I had ever written and thought it was going nowhere. And I actually think it was biggest song I have written so far.”
