Lydiard Millicent is a village and civil parish in Wiltshire, England, about 3+1⁄2 miles (6 km) west of the centre of Swindon.

Lydiard Manor is mentioned in the Domesday survey of 1086, owned by Geoffrey de Clinton, with 25 households.

[4] There was an extensive Romano-British ceramic manufacturing industry on and around Shaw Ridge, on land formerly within the two Lydiard parishes, mainly in the 2nd century.

[8] A Primitive Methodist chapel was built in 1863 at Lydiard Green, of red brick in plain classical style.

The parish registers kept in the Wiltshire and Swindon History Centre cover the years 1579–1968 (baptisms), 1580–1992 (marriages), and 1580–1988 (burials).

Northern European in style, with rock-faced limestone walls dressed with Bath stone, English Heritage describe it as "a fine example of a mid C19 rectory of substance".

[26] There is a parish hall (1965),[27] a recreation field with changing rooms (2002),[28] a used car garage, and a pub, the Sun Inn.
