The Belgium national under-19 football team is the national under-19 football team of Belgium and is controlled by the Belgian Football Association. The team competes in the European Under-19 Football Championship, held every year. Their biggest success was winning the tournament in 1977, albeit it wore a different name and had a different structure back then.
