Neoclassical architecture (French: Architecture néoclassique) appeared in Belgium during the period of Austrian occupation in the mid-18th century and enjoyed considerably longevity in the country, surviving through periods of French and Dutch occupation and the birth of Independent Belgium, surviving well into the 20th century.

It is possible to divide the architects and their major works according to the diverse phases of neoclassicism in Belgium and the distinct periods of political occupation.
Since the period of French occupation was characterized by the long-running French Revolutionary and Napoleonic Wars, few outstanding neoclassical works were constructed.
In 1815, the Southern Netherlands were united by the Congress of Vienna with the Dutch United Provinces to form the new Dutch-led "United Kingdom of the Netherlands".
