William K. Harmon (born 23 December 1994) is a New Zealand rugby union player who currently plays as a flanker for Canterbury in New Zealand's domestic Mitre 10 Cup and the Highlanders in Super Rugby.
Harmon played for New Brighton before High School. Harmon attended St Bede's College in Christchurch and during that time, he was selected as a member of the New Zealand Schools Barbarians squad for their matches against Australia and Samoa in 2012.
After leaving school, Harmon played for New Brighton again in club rugby while working full-time as a plumber. He was in excellent form during the 2016 club rugby season, captaining New Brighton to the final of the Hawkins Division 1 Trophy. Unfortunately, the season didn't end well for him as he was red carded as his side went down to Lincoln University.
Harmon was named in Canterbury's squad for the 2016 Mitre 10 Cup. He debuted in the first match of the season, a 43-3 victory over Auckland and went on to make 7 appearances and score 3 tries during the campaign which culminated in Canterbury lifting the Premiership title for the 8th time in 9 seasons as well as claiming the Ranfurly Shield.
At the end of 2020, Harmon signed a two year deal to play for the Highlanders in Super Rugby.
