Fulk IV (French: Foulques IV d'Anjou; 1043 – 14 April 1109), better known as Fulk le Réchin (Latin: Fulco Rechin), was the count of Anjou from around 1068 until his death. He was noted to be "a man with many reprehensible, even scandalous, habits" by Orderic Vitalis, who particularly objected to his many women and his influential footwear, claiming he popularized the pigaches that eventually became the poulaine, the medieval long-toed shoe.
