Gregory Sedoc (born 16 October 1981) is a Dutch retired hurdler.

He reached his first international final at the 2007 European Indoor Championships in 60 metres hurdles, and won the event, equalling his personal best time of 7.63 seconds which was established in the previous rounds and beating fellow-countryman Marcel van der Westen by 0.01 second.

I never thought I would be able to become European champion... Getting a one-two in the final has never happened to the Netherlands before and it's fantastic.

"[1] Sedoc followed this up with a silver medal at the 2009 European Indoor Championships.
