Harlaxton Manor is a Victorian country house in Harlaxton, Lincolnshire, England. It was built for Gregory Gregory, a local squire and businessman. Gregory employed two of the leading architects of Victorian England, Anthony Salvin and William Burn and consulted a third, Edward Blore, during its construction. Its architecture, which combines elements of Jacobean and Elizabethan styles with Baroque decoration, makes it unique among England's Jacobethan houses. Harlaxton is a Grade I listed building on the National Heritage List for England, and many other structures on the estate are also listed. The surrounding park and gardens are listed Grade II* on the Register of Historic Parks and Gardens. It is now the British campus of the University of Evansville.
