The Battle of Largs (2 October 1263) was an indecisive engagement between the kingdoms of Norway and Scotland near Largs, Scotland. The conflict formed part of the Norwegian expedition against Scotland in 1263, in which Hakon Hakonarson, King of Norway attempted to reassert Norwegian sovereignty over the western seaboard of Scotland. Since the beginning of the 12th century this region had lain within the Norwegian realm, ruled by magnates who recognised the overlordship of the Kings of Norway.
