The Open de Saint-Omer is a European Tour event which takes place in June. The current champion is David Dixon from England. The tournament takes place at Aa St.Omer Golf Club in Lumbres, France. The event has been part of the European Tour since 2003.

It takes place the same week as the US Open and has a small prize fund compared to other events. As a result many of the leading players are absent and it gives the lesser ranked players a chance to make a name for themselves as David Dixon did in 2008.
