The Tour of Belgium (Ronde van België/Tour de Belgique) is a five-day bicycle race which is held annually in Belgium.
It was held annually between 1908 and 1981, except during both world wars. Between 1982 and 1990 several races were not organised and none at all during the decade 1991 to 2001. From 2002 onwards the race has again become an annual fixture on the cycling calendar.
Following the start of the UCI ProTour in 2005 it looked like the race would merge with the Eneco Tour; however this has not happened and it is now part of the UCI Europe Tour competition.
