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.

The County of Anjou was a French county that was the predecessor to the Duchy of Anjou. Its capital was Angers, and its area was roughly co-extensive with the diocese of Angers. Anjou was bordered by Brittany to the west, Maine to the north, Touraine to the east and Poitou to the south. Its 12th century Count Geoffrey created the nucleus of what became the Angevin Empire. The adjectival form is Angevin, and inhabitants of Anjou are known as Angevins. In 1360, the county was raised into the Duchy of Anjou within the Kingdom of France. This duchy was later absorbed into the French royal domain in 1482 and remained a province of the kingdom until 1790.
