Sir John Henry Fludyer, 4th Baronet (1803–1896), generally known as Henry Fludyer, was an English baronet and clergyman who restored St Nicholas' Church in Thistleton, Rutland, as a memorial to his three eldest children. He inherited the baronetcy at a late age after his cousin and two elder brothers died without issue. He inherited the family seat at Ayston, a village where he was already rector, and near which he seems to have spent most of his life. He died at age 92, having been connected to the parish of Ayston for nearly 70 years.
