Easton Neston is a country house near Towcester, Northamptonshire, England, and is part of the Easton Neston parish. It was designed in the Baroque style by the architect Nicholas Hawksmoor. Easton Neston is thought to be the only mansion which was solely the work of Hawksmoor. From circa 1700 Hawksmoor was to work on many buildings, including Castle Howard and Blenheim Palace, with Sir John Vanbrugh, often providing the technical knowledge to the less qualified Vanbrugh. Hawksmoor's work, even after their many collaborations, was always more classically severe than Vanbrugh's. However, Easton Neston predates this partnership by some six years. The house is a Listed building Grade I.
