Legbourne Priory was a priory in the village of Legbourne, Lincolnshire, England. Founded by Robert Fitz Gilbert around 1150, the priory was for the nuns of Keddington (sometimes Hallington). The earliest visitation that survives is from 1440 when Bishop Alnwick reported a few irregularities which needed correction, but found most fault with the Prioress. She had been too fond of entertaining her own relations, and partly supported them with revenue from the priory. She had admitted an unlicensed chaplain to preach in the church, and counselled her nuns not to report anything amiss at the visitation.
