Milefortlet 2 was a Milefortlet of the Roman Cumbrian Coast defences. These milefortlets and intervening stone watchtowers extended from the western end of Hadrian's Wall, along the Cumbrian coast and were linked by a wooden palisade. They were contemporary with defensive structures on Hadrian's Wall. The exact location of Milefortlet 2 is unknown, although one of the nearby turrets (Tower 2B) has been located and excavated.
