Kilmahog (Scottish Gaelic: Cille MoChùig: Cell of St. Chug[1]) is a hamlet situated half a mile to the west of Callander, Scotland.

[2] Kilmahog lies on the Garbh Uisge, also known as the "River Leny", at the junction of the Trossachs and Lochearnhead roads.

[7][8] Nearby, the remains of first century Roman ramparts attributed to the campaigns of Agricola can be seen at Bochastle in the fields to the east of the former railway.

The fortification was constructed during the Flavian occupation in Scotland around 80 CE and it may have served as a northern fort of the Gask Ridge frontier.

All that remains of the chapel is a small burial ground with stones dating back to the late 17th century.

The former Callander and Oban Railway line passed through Kilmahog; the trackbed is now part of the National Cycle Network (route 7)[11] and the Rob Roy Way.
