This is a general survey on the historical and modern presence of Freemasonry in Belgium.
Several Grand Lodges are active in Belgium.
The Regular Grand Lodge of Belgium (R.G.L.B.) is currently the only Belgian Grand Lodge which is recognised as regular by UGLE and its concordant jurisdictions.
The oldest Grand Lodge of Belgium, the Grand Orient of Belgium (G.O.B.) lost its recognition by the UGLE in the 19th century when it decided to remove the requirement for Masons to have a belief in a Supreme Being. In an attempt to regain recognition by the UGLE, five lodges from the GOB founded the Grand Lodge of Belgium (G.L.B.) in 1959. When in 1979 the G.L.B. also lost its recognition by UGLE, nine lodges founded the Regular Grand Loge of Belgium on 15 June 1979.
