Tim de Cler (born 8 November 1978) is a Dutch former professional footballer who played as a left-back for Ajax, AZ, Feyenoord and AEK Larnaca.

[2] At Ajax, De Cler played at first as a left winger, but eventually he was positioned as a left-back when he reached the A-level in youth football.

[2] That season, Ajax won both the Eredivisie and the KNVB Cup, and although these were De Cler's first official trophies, there were mixed feelings due to his injury.

[citation needed] During his time at Ajax, De Cler had tough competition from fellow defenders Cristian Chivu, John O'Brien and Maxwell, but nonetheless managed to play many matches.

It was the start of a unique period in which AZ found themselves improving among the three historical giant teams in the Netherlands and even in Europe; that is, Ajax, Feyenoord and PSV.

[2][3] Having parted company with Feyenoord, De Cler signed a two-year contract with the Cypriot First Division side AEK Larnaca on 30 June 2011 following a suggestion from the club's head coach, Jordi Cruyff.

He had been a regular member of the Dutch national team since Marco van Basten took over as coach in August 2004 and was selected for the 2006 FIFA World Cup and UEFA Euro 2008.
