Nantwich was a parliamentary constituency in Cheshire which returned one Member of Parliament (MP) to the House of Commons of the Parliament of the United Kingdom, elected using the first-past-the-post voting system.

Nantwich was created for the 1955 general election from parts of the Crewe and Northwich constituencies.

Middlewich, Winsford, the southern part of the Rural District of Tarvin (including Malpas) and a small part of the Rural District of Northwich were transferred from Northwich.

[2] From 1 April 1974 until the constituency was abolished at the next boundary review which came into effect for the 1983 general election, the constituency comprised parts of the expanded City of Chester and newly formed Boroughs of Crewe and Nantwich, and Vale Royal, but its boundaries were unchanged.

On abolition, Nantwich and surrounding rural areas were included in Crewe and Nantwich; Malpas and Winsford in Eddisbury; and Middlewich in Congleton.
