Alasdair Caimbeul or Alexander Campbell of Carco (died February 1608) was a Scottish noble and prelate. Coming from a branch of Clan Campbell in the allegiance of the Earl of Argyll, his career began in the 1560s still only a minor, serving the Earl of Argyll's interest. He was made Bishop of Brechin, and almost immediately alienated the majority of the bishopric's historical resources into the hands of the earl.
