The Count of Anjou was the ruler of the County of Anjou, first granted by King Charles the Bald of West Francia in the 9th century to Robert the Strong. Ingelger and his son, Fulk the Red, were viscounts until Fulk assumed the title of count.

Ingelger's male line ended with Geoffrey II. Subsequent counts of Anjou were descended from Geoffrey's sister Ermengarde and Count Geoffrey II of Gâtinais. Their agnatic descendants, who included the Angevin kings of England, continued to hold the title and territory until King Philip II Augustus seized the region and annexed it to the French crown lands.

In 1290, Margaret married Charles of Valois, the younger brother of king Philip IV of France. He became Count of Anjou in her right.

In 1328, Philip of Valois ascended the French throne and became King Philip VI. At this time, the counties of Anjou, Maine, and Valois returned to the royal domain. On 26 April 1332, Philip granted the county to his eldest son, John:

Following John's ascension to the throne as John II in 1350, the title again returned to the royal domain.
