Iseabail Ní Mheic Cailéin, Gaelic noblewoman and poet, fl. 1500.
A daughter of Colin Campbell, 1st Earl of Argyll (died 1493). Three poems by her are preserved in the Book of the Dean of Lismore - Atá fleasgach ar mo thí, Éistibh, a Luchd an Tighe-se and Is mairg dá ngalar an grádh.
Thomas Owen Clancy Clancy notes that Éistibh, a Luchd an Tighe-se "is a fairly obscene boast to the court circle on the size and potency of her household priest's penis. The authenticity of the attribution to Iseabail has been questioned, but without substantial grounds."
