The Château d'Angers is a castle in the city of Angers in the Loire Valley, in the département of Maine-et-Loire, in France. Founded in the 9th century by the Counts of Anjou, it was expanded to its current size in the 13th century. It is located overhanging the river Maine. It is a listed historical monument since 1875. Now open to the public, the Château d'Angers is home of the Apocalypse Tapestry.

The count of Anjou was the ruler of the County of Anjou, first granted by Charles the Bald in the 9th century to Robert the Strong. Ingelger and his son, Fulk the Red, were viscounts until Fulk assumed the title of count. The Robertians and the Capetian kings were distracted by wars with the Vikings and other concerns and were unable to recover the county until the reign of Philip II Augustus, more than 270 years later.
