Lucy of Bolingbroke or Lucia Thoroldsdottir of Lincoln (died circa 1136) was an Anglo-Norman heiress in central England and, later in life, countess of Chester. Probably related to the old English earls of Mercia, she came to possess extensive lands in Lincolnshire which she passed on to her husbands and sons. She was a notable religious patron, founding or co-founding two small religious houses and endowing several with lands and churches.
