Minden-Ravensberg was a Prussian administrative unit consisting of the Principality of Minden and the County of Ravensberg from 1719–1807. The capital was Minden. In 1807 the region became part of the Kingdom of Westphalia, a client state of Napoleonic France. The territory was restored to Prussia after the Napoleonic Wars and became part of the new Prussian Province of Westphalia in 1815.
