Erwin Koeman (Dutch pronunciation: [ˈɛrʋɪn ˈkumɑn]; born 20 September 1961 in Zaandam, North Holland) is a retired professional football player and became subsequently a Dutch football manager. He is currently the assistant head coach of Everton.
He is the son of Dutch international footballer Martin Koeman, and, alongside his younger brother Ronald, has also represented the Netherlands. All three Koemans played for Groningen at some time during their careers. Erwin Koeman's son, Len, is also a footballer and currently plays for the Helmond Sport youth team.
Koeman played with Groningen, Mechelen, where he won the Belgian League in 1989 and 1988 Cup Winners' Cup during the team's heyday and PSV, where they became league champions in 1990–91 and 1991–92.
Koeman finished his playing career with Groningen in 1998 and became youth coach at PSV. In October 2001, he was promoted to assistant manager under Eric Gerets, and for the 2004–05 season became manager in RKC Waalwijk. He managed RKC for one season before moving to Feyenoord. In March 2006, he extended his contract to the summer 2009. However, on 3 May 2007, Koeman announced his immediate resignation due to motivational problems, after a troublesome season, where Feyenoord eventually finished seventh.
Before the 2011–12 season, he was appointed as the new manager of FC Utrecht. However, on 18 October 2011 he quit the job citing bad working conditions and frustration after several key players had been sold.
