Fortrose (with Rosemarkie) in Ross-shire was a burgh constituency that elected one commissioner to the Parliament of Scotland and to the Convention of Estates.
After the Acts of Union 1707, Fortrose, Forres, Nairn and Inverness formed the Inverness district of burghs, returning one member between them to the House of Commons of Great Britain.
