Folke the Fat (Swedish: Folke den tjocke), according to Gesta Danorum by the 12th century Danish chronicler Saxo Grammaticus, was the most powerful man in Sweden around 1100. He married Ingrid Knutsdotter, daughter of the Danish king Canute IV of Denmark who was murdered in 1086. Folke and Ingrid had the sons Knut and Benedict according to Saxo. The chronicler furthermore reports that Folke was the paternal grandfather of Birger Brosa, who still was alive at the time he wrote.
