Steeple Langford is a village and civil parish in the English county of Wiltshire, 6 miles (10 km) northwest of Wilton.

However, early forms of the name include 'Stapel', 'Steppul', and 'Staple' Langford, and one writer on the origin of the place-name has suggested that "the prefix Staple sometimes indicates that to a town was granted the privilege of holding a market.

Neolithic finds in the parish include flint tools, a polished axehead and pottery, as well as a bowl barrow and the remains of a round barrow; from the Bronze Age axeheads, a palstave and a chisel;[4] from the Iron Age pottery, a rotary quern fragment and a circular enclosure; from the Romano-British period coins, a polished and painted pebble,[4] and a needle; from the Saxon period a spearhead and a silver brooch; medieval strip lynchets; and field systems and earthworks of various dates.

[7][8] In the time of King Edward III, John de Steeves held Steeple Langford in return for a knight's service.

[3] As result of the Penruddock uprising of 1655, three men of the parish, Nicholas Mussell, yeoman, and Henry Collyer and Joseph Collier, gentlemen, were found guilty of high treason against Oliver Cromwell.

As a child of about ten in the 1770s, William Cobbett spent a whole summer in the village, and his happy memories of his stay led him to take one of his 'Rural Rides' into Wiltshire some fifty years later.

[13] The Warminster to Salisbury road running through Steeple Langford village[14] was designated as the A36 in the 20th century, and became part of the Southampton-Bristol route.

[19] Most of the interior is 18th-century, and in a drawing room is a fine white marble fireplace in late-18th Gothick style with elaborate carving, said to have come from Fonthill.

The top stage of the tower was added in the 15th century; in 1857 the chancel was rebuilt in 1857 by William Slater using coursed flint, and extensive restoration in 1875 by R. H. Carpenter included re-roofing and addition of a vestry.

[26] A carved medieval roof boss in the north aisle of the church represents a dog, its body coiled and surrounded by foliage.

[27] In 1857, when the chancel of the church was demolished for rebuilding, a slab of Purbeck marble was found, about 26 inches by 14, bearing an incised portrait of a man wearing a long robe, his hands raised to hold a plain shield or receptacle, with a horn hanging on a strap from his left shoulder.

[29] John Murray noted in 1859 that the church "contains a rich altar-tomb to one of the family of Mompesson, but it has long lost the steeple which formerly distinguished it".

[33] The parish registers now held in the Wiltshire and Swindon History Centre cover the years 1674–1924 (christenings), 1674–1980 (marriages), and 1674–1873 (burials).

[35] Baptists built a small redbrick chapel in 1849 at Hanging Langford, which was attended by a total of 125 at three services on Census Sunday in 1851; it was closed in 1960.

The reserve has an area of fifty acres, and species include mallard, gadwall, tufted duck, common pochard, northern shoveller, Eurasian wigeon, kingfisher, great crested grebe, common tern, osprey, brown trout, greyling, otters, and water voles.
