Dun Troddan (Scottish Gaelic: Dùn Trodan) is an iron-age broch located about 5 kilometres (3.1 mi) southeast of the village of Glenelg, Highland, in Scotland.

Dun Troddan (grid reference NG83401724) stands on a level rock platform north of the Abhainn a’ Ghlinne Bhig, in the lower reaches of Gleann Beag.

[3] The broch was visited by Thomas Pennant in 1772, and it was still a substantial structure, although it had lost the upper gallery by this time.

[3] On the left side of the entrance passage is a small side-chamber, sometimes called a "guard cell".

[3] The broch has features now missing from Dun Telve; these include a number of postholes in the floor and a hearth.
