The Duke of Limiport is a title in the peerage of Ikonia named after the town of Limiport. Created in 2019, Aidan McGrath became the first holder of the title, before later having it revoked on 25 May 2019 due to the foundation of the United People's Republic of Quebec. Later, on reconsideration in 2020, the Ikonian monarch restored his position. McGrath later forcefully removed his peerage.
The family and the Duke, through Ikonian peerage law, meet yearly in the Royal Peerage Conference.
