Langwathby is a village and civil parish in northern Cumbria, and in the historic English county of Cumberland, about 5 miles (8 km) north east of Penrith on the A686 road.

Langwathby is the base of the 'Pride of Cumbria', one of the helicopters run by the Great North Air Ambulance Service 'Langwathby' can be translated as 'long' ('lang'), 'ford' ('wath', Old Norse 'vað'), 'village' (Old English 'bȳ', Old Norse 'býr'), referring to the fording of the River Eden which runs along the edge of the village.

The ford which gave the village its name was replaced by a three-arched sandstone toll bridge, which was washed away in 1968.

This ward stretches north east to Gamblesby and south to Edenhall with a total population taken at the 2011 Census of 1,562.

At Barbary Plains just outside Edenhall, there was formerly a cement block works formerly owned by Hanson plc and later by RMC Group, part of Cemex.
