Five Thirty, sometimes written 5:30, were a three-piece rock band from London, England, briefly popular in the early 1990s.

Tara Milton and Nick Baker formed Five Thirty (sometimes written 5:30!) whilst still at school near Oxford in 1983. They met and recruited drummer Steve Beatty and played their first official gig in May 1984. This initial line-up played a number of gigs - including support slots for The Truth, Makin' Time and Direct Hits.
