Simon Digby (died 1495) was an English antiquary and Constable of Coleshill, in Warwickshire in the 15th century.
Simon de Montford was executed in 1495 for contributing to the fund of Perkin Warbeck, who was plotting to oust King Henry VII from the throne. During de Montford's imprisonment in the Tower of London, the King granted his lands at Coleshill to Simon Digby as he was Constable. Descendants of Simon Digby (Wingfield-Digby) still hold the titles.
