Kilmun (Scottish Gaelic: Cill Mhunna) is a linear settlement on the north shore of the Holy Loch in Argyll and Bute, Scotland.

It takes its name from the 7th-century monastic community founded by an Irish monk, St Munn (Fintán of Taghmon).

Like them, it developed as a watering-place (a summer pleasure resort/spa with sea bathing for well off Glasgow families) after 1827, when a quay was built by the marine engineer David Napier to connect to his "new route" to Inveraray which included a steam ship on Loch Eck.

The complex is located on the summit of a slight knoll about ten metres from the shoreline of the Holy Loch.

A series of woodland walks have been established of varying gradients and degrees of difficulty, which link by a forestry track to Benmore wood at the top of Puck's Glen.
