Cissa of Crowland was a saint in the medieval Fenlands. He was the successor of Guthlac as abbot of Crowland, and is mentioned in Felix' Vita Guthlaci.[2] According to the Crowland Chronicle his tomb was next to Guthlac's, and like the tomb of Guthlac, was destroyed by the Scandinavians.[2] His relics were translated to Thorney Abbey in the 10th-century.[2]
