John Lowe (born 21 July 1945) is an English former darts player. Along with Eric Bristow and Jocky Wilson, he was known for dominating darts during the 1980s. Lowe was world champion on three occasions, in 1979, 1987 and 1993. He was also a two-time winner of the Winmau World Masters and a two-time World Cup singles champion.

Lowe achieved the first ever televised nine-dart finish (the sport's equivalent of a 147 break in snooker) on 13 October 1984 during the World Matchplay tournament against Keith Deller, although it was not live and instead shown on a highlights programme on ITV. Lowe won £102,000 for this success. He went on to win the tournament.

A nine-dart finish, also known as a nine-darter, is a perfect leg in the sport of darts, using only nine darts, the fewest possible, to check out from 501.

Although many other combinations are possible, the traditional nine-dart finish requires a score of 60 (treble 20) with each of the first six throws: that is, with the first two shots of three. That leaves 141 to score on the final shot (of three darts), known as the outshot.

This outshot is traditionally performed in one of three ways:

treble 20 (60), treble 19 (57) and double 12 (24)

treble 20 (60), treble 15 (45) and double 18 (36)

treble 17 (51), treble 18 (54) and double 18 (36)

Another way is to score 167 with each set of three darts, scoring a perfect 501 total, in the following way:

treble 20 (60), treble 19 (57) and bullseye (50)
