"U-Turn" was the fourth international single taken from Usher's 2001 album 8701. The song was a dance track produced by Jermaine Dupri and was a departure from the previous two smooth ballad singles that had been released from the album. The track reached the top 10 in Australia, the top 20 in the UK and Switzerland and was a top 40 hit in the Netherlands. The single was not released in the US.

The song was written by Usher, Dupri and Brian Michael Cox who co-wrote four songs on the album including hit single "U Got It Bad". The song also references Bobby Brown and also refers to the crunk style of rap making it one of the first mainstream r&b tracks to refer to that style.
