Burghley House (/ˈbɜːrli/) is a grand sixteenth-century English country house near Stamford, Lincolnshire. It is a leading example of the Elizabethan prodigy house, built and still lived in by the Cecil family. The exterior largely retains its Elizabethan appearance, but most of the interiors date from remodellings before 1800. The house is open to the public and displays a circuit of grand and richly furnished state apartments. Its park was laid out by Capability Brown.
The house is on the boundary of the civil parishes of Barnack and St Martin's Without in the Peterborough unitary authority of Cambridgeshire. It was formerly part of the Soke of Peterborough, an historic area that was traditionally associated with Northamptonshire. It lies 0.9 miles (1.4 km) south of Stamford and 10 miles (16 km) northwest of Peterborough city centre.
