The Fort of Aubin-Neufchâteau () is a Belgian fortification located near Neufchâteau. The fort was built in the 1930s as part of the fortified position of Liège, augmenting the twelve original forts built to defend Liège in the 1880s with four more forts closer to the Belgian frontier with Germany. The fort surrendered to German forces in the opening days of World War II, following the dramatic assault on Aubin-Neufchâteau's sister fort, Fort Eben-Emael. Aubin-Neufchâteau has been preserved and may be visited by the public.
