George Leonard Jenyns (19 June 1763–1848) was an English priest, a landowner involved both in the Bedford Level Corporation and in the Board of Agriculture.
He was the son of John Harvey Jenyns of Eye, Suffolk, and was born at Roydon, Norfolk.
He became Dean and rhetorical praelector of his college in 1787, though not a fellow, this being the first recorded instance.
[2][3] He was vicar of Swaffham Prior, Cambridgeshire 1787–1848 and prebendary of Ely Cathedral, 1802–1848.
[4] At Bottisham Hall he built a new house, constructed for him by 1797; and also expanded the Jenyns estate by purchases.
