Louis Johannes Koen (born 7 July 1975 in Cape Town, South Africa) is a South-African rugby union player who played for the Springboks, until 2003, when he moved abroad following the World Cup.
Effective at either fly half or full back, his career began with Western Province, before his move to the Lions and later the Bulls. He was part of the Western Province team that won the Currie Cup in 1997, contributing immensely with his accurate goal kicking. It was this dependable boot that led to his recall to the Springbok team in 2003 after a two-year absence, but following a difficult tournament[1] and South Africa's disappointing exit in the quarter-finals, Koen was signed by Narbonne in France. After two years dogged by injury, Koen moved back to Western Province as only the second full-time kicking coach in South Africa.[2] In 2010 he was recalled out of retirement to play one Currie Cup First Division match for the Boland Cavaliers against the Valke.
He made his debut for South Africa against Australia on 8 July 2000.
He played four matches in the 2003 Rugby World Cup. During the game between South Africa and Samoa, as Koen prepared to take a conversion, a drunk rugby fan ran onto the field and attempted to tackle Koen, knocking himself out. Koen succeeded with the conversion.[3]
(as of 31 December 2005)
In February 2022, Koen, then the South African Rugby Union's high-performance manager, was appointed to assist Heyneke Meyer with the Houston SaberCats.[4]
In March 2023, Koen was appointed interim coach of the South Africa women's national rugby union team.[5]
