Argyll is of ancient origin, and corresponds to most of the part of the ancient kingdom of Dál Riata on Great Britain. Argyll was also a medieval bishopric with its cathedral at Lismore, as well as an early modern earldom and dukedom, the Dukedom of Argyll.
It borders Inverness-shire to the north, Perthshire and Dunbartonshire to the east, and—separated by the Firth of Clyde—neighbours Renfrewshire and Ayrshire to the south-east, and Buteshire to the south.
Between 1890 and 1975, Argyll was an administrative county with a county council. Its area corresponds with most of the modern council area of Argyll and Bute, excluding the Isle of Bute and the Helensburgh area, but including the Morvern and Ardnamurchan areas of the Highland council area.
