"Can We Fix It?" is the name of the theme song from the British preschool animated television programme Bob the Builder. It was written by Paul K. Joyce and produced by Hot Animation. The song's title is derived from the catchphrase of the programme's titular character, and the chorus of the song features this phrase prominently, as well as the response, "Yes we can!" Vocals on the song are provided by Neil Morrissey, who voiced Bob at the time of the track's recording. It was released as a single on 4 December 2000 in the United Kingdom.

"Can We Fix It?" became the UK Christmas number-one single of 2000, beating Westlife's "What Makes a Man" to the top spot. It was the biggest-selling single of the year in the United Kingdom, appearing 10th on the decade-end chart and 80th on the all-time UK best-sellers list. The song has sold over one million copies in the United Kingdom, according to the Official Charts Company. On 13 August 2001, the song was released in Australia and reached number one that September, becoming the ninth-best-selling single of the year there.

A second single by Bob the Builder, "Mambo No. 5", with the lyrics adapted from Lou Bega's 1999 hit version, also reached number one on the UK chart in September 2001. An album entitled The Album followed, which debuted at number four on the UK Albums Chart.
