Syresham is a village and civil parish in the English district of South Northamptonshire. It is near Brackley town and close to Silverstone Circuit. It is surrounded by villages and hamlets such as Biddlesden, Whitfield, Northamptonshire, Helmdon, Silverstone and Wappenham, and the border with Buckinghamshire lies just to the south of the village. The border itself is defined by the River Great Ouse, which rises within the parish. There are two small hamlets in the parish, Crowfield and Pimlico.
The local geology includes the cornbrash and oolitic limestone of Jurassic age. There is a large abandoned quarry north of the church which supplied the stone for many of the older buildings in the village. The population, like so many other villages in England, is now much lower than even a century ago due to the British agricultural revolution. There are the remains of a very large fish pond south of the church and close to the manor house. The dam wall still stands but the pond was drained long ago for its rich pasture.
