Kilmun Parish Church and Argyll Mausoleum in Kilmun, Argyll and Bute, Scotland, consists of St Munn's Church (a Category-A-listed building but no longer a parish church of the Church of Scotland), as well as the adjacent mausoleum of the Dukes of Argyll and a historically significant churchyard. The complex is located on the summit of a slight knoll about ten metres from the shoreline of the Holy Loch on the Cowal Peninsula in Argyll, Scotland. The existing church dates from 1841 and occupies the site of an older, medieval church. A partly ruined tower from the medieval period still stands to the west of the present building.
