Nicola de la Haie (born c. 1150; d. 1230),[1] of Swaton in Lincolnshire, (also written de la Haye) was an English landowner and administrator who inherited from her father not only lands in both England and Normandy but also the post of hereditary constable of Lincoln Castle. On her own, she twice defended the castle against prolonged sieges. After the death of her second husband in 1214, she continued to hold the castle until she retired on grounds of old age in 1226.[2][3]
On 18 October 1216, she was also appointed sheriff of Lincolnshire by King John.[4][5]
