Legsby (otherwise Legesby) is a small village and civil parish in the West Lindsey district of Lincolnshire, England.

In 1066 Alsi son of Godram held the lordship of the manor, transferred to Everard of Leathley in 1086, with Tenant-in-Chief becoming William of Percy.

[6] Bleasby, less than 1 mile (1.6 km) to the south, is the site of a deserted medieval village and manor house, defined by moat, croft, field and pond earthworks.

[10] The settlement remains of the Legsby hamlet of Holtham, in the 16th century known as Howdome and comprising four families, is defined by crop mark evidence of a moated monastic or manor house, and a ridge and furrow field system.

Machinery finds could indicate a 16th- or 17th-century mill, and moat, pond, ditch, croft and field earthworks of a defensive homestead.

[13] East Torrington, 1.5 miles (2.4 km) south-east of Legsby, contains earthworks adjacent to the north-west of the church, with rectilinear ditches, a hollow way, and ridge and furrow field system, indicating a medieval village.

[15] Pevsner records that the church was probably altered in the 18th century, with a shortening of the chancel, and has a Norman font, Kelly's giving it Romanesque attribution, and a chalice and paten cover dated 1569.
