Pseudo-Ingulf is the name given to an unknown English author of the Historia Monasterii Croylandensis, also known as the Croyland Chronicle. Nothing certain is known of Pseudo-Ingulf although it is generally assumed that he was connected with Croyland Abbey.

The Historia Monasterii Croylandensis is attributed to Abbot Ingulph, an 11th-century Abbot of Croyland, but is generally accepted to be a 14th-century work.
