This article lists diplomatic missions resident in the Kingdom of Belgium. This listing excludes honorary consulates.
At present, the capital city of Brussels hosts 183 embassies. Brussels is unique in that it is not only the seat of the Belgian Government, but also of the European Commission, which is the executive wing of the European Union to which countries accredit representatives, and of the NATO. Thus, a country can maintain up to three missions in Brussels: one to Belgium, one to the EU, and one to the NATO. Some embassies serve all three functions, while other countries open separate embassies for each, or combine any two of the functions in one embassy.
