Ipswich Greyfriars was a mediaeval monastic house of Friars Minor (Franciscans) founded during the 13th century in Ipswich, Suffolk. It was said conventionally to have been founded by Sir Robert Tibetot of Nettlestead, Suffolk (before 1230–1298), but the foundation is accepted (by Knowles and Hadcock) to be set back before 1236 (and therefore before Sir Robert's time). This makes it the earliest house of mendicant friars in Suffolk, and established no more than ten years after the death of St Francis himself. It was within the Cambridge Custody. It remained active until dissolved in the late 1530s.
