Milton Lilbourne is a village and civil parish in the county of Wiltshire, England, in the Vale of Pewsey between Pewsey and Burbage. It is largely a mixed residential area centred on the Manor. The nearest town is Marlborough, 5.5 miles (8.9 km) to the north.

The parish includes the following hamlets:

The parish is unusual in that it has a long thin shape and is one of the few to have boundaries on the uplands to both south and north of the Vale. The southern boundary passes by a long barrow and the northern one abuts the prehistoric fort on Martinsell Hill.

The parish contains several prehistoric features including the Giants Grave to the south (a Neolithic long barrow) and a Bronze Age Barrow Cemetery at Milton Hill Farm.

"Milton" in the village's name probably derives from its position as "middle tun" between Pewsey and Easton Royal, the "east tun". "Lilbourne" is from Lillebonne, the surname of lords of the manor.

The Manor House dates from c.1710 and is Grade II* listed.

There was a vicarage here by 1195. The parish church of St Peter is in squared and coursed rubble with stone dressings, and ashlar copings and battlements. When the chancel was rebuilt in the 14th century, the jambs of the arch of the 12th-century church were retained; the four-bay north arcade is from the 13th century.

Restoration of the chancel in 1859 was to designs of G.E. Street, and in 1875 J. L. Pearson retired the nave, aisle and porch. The northwest tower has six bells, five of them cast by Robert Wells II in 1789. The building was recorded as Grade II* listed in 1959.
