The name Longdon is derived from two Old English words, lang and dūn, meaning long hill. A settlement at Longdon-Upon-Tern dates to at least the Normans, as it is mentioned in the Domesday Book of 1086 as Languedune, held by St. Alkmund's Church. It continued with the church until the 12th century when it passed to Lilleshall Abbey until its dissolution in the 16th century. Its Domesday assets were: 2 hides, 5 ploughs, and a mill worth 5s.
Parish
Longdon-Upon-Tern is an ecclesiastical parish. In 1988 it merged with Rodington ecclesiastical parish, a close by village, to create the Civil Parish of Rodington with a parish council, to relieve civil responsibilities from the two ecclesiastical parishes. The civil parish boundaries now include the areas of Long Waste, Long Lane, Isombridge, Marsh Green, Sugdon, Rodington, Rodington Heath, and Longdon-Upon-Tern. Although the two separate parishes have now merged into a civil parish with a parish council, the two distinct ecclesiastical parishes maintain both village halls hosting varied community activities.

Aqueduct
The village is particularly notable as the location of the world's first large-scale cast iron navigable aqueduct. Designed by Thomas Telford, the aqueduct opened in 1797 as part of the Shrewsbury Canal. Telford built the cast iron aqueduct to replace a stone aqueduct, originally built by Josiah Clowes, which was swept away by floods in 1795. Although the canal was abandoned in 1944 due to the shift in traffic to the rail networks, the aqueduct remains. It is Grade I listed and a scheduled ancient monument, situated in fields astride the River Tern. The monument is signposted and visible from the road. Clearly marked footpaths lead directly to the monument from a small roadside car park. Telford later designed and built the very much larger Pontcysyllte Aqueduct in Wales, now designated as a World Heritage Site.
