Branthwaite is a hamlet in the borough of Allerdale, Cumbria. Branthwaite is approximately 5 mi (8.0 km) from Workington and is 7 mi (11 km) from Cockermouth; the small village has few amenities but is a sought after area. There is one public house, The Wild Duck. The River Marron runs through Branthwaite. There was once a trout farm but it has recently closed down. There is also an old mill, which was the main source for the village, but again this has long closed down and is now home to the local motor engineering business. Branthwaite Hall is an old peel tower that is in between Branthwaite and Dean.
