Schloss Oldenburg is a schloss, or palace, in the city of Oldenburg in the present-day state of Lower Saxony, Germany. The first castle on the site was built around 1100 and became the ancestral home of the House of Oldenburg. The present building served as residence to the counts (1667–1785), dukes (1785–1815) and grand dukes (1815–1918) of Oldenburg.
