Muckle Alicompen is a pair of waterfalls on the Kirk Burn in Campsie Glen, near the village of Clachan of Campsie in East Dunbartonshire, Scotland. The site sits along a popular waterfall walk within easy reach of Glasgow.

The two falls offer distinct geological interest.

The upper waterfall cascades over a basalt lava flow belonging to the Clyde Volcanic Formation — specifically a hawaiite, a high-alkali basalt in which small white feldspar crystals can be seen oriented parallel to the original flow direction.

The lower, larger waterfall pours over a substantial igneous dyke. Thin layers of red bole between lava flows record periods of tropical weathering at the tops of ancient flows, evidence of the region's deep geological past.

Muckle Alicompen sits close to its smaller companion, Wee Alicompen, and is a waypoint on several walking routes into the Campsie Fells. Visitors are advised not to continue upstream beyond the falls, as fallen trees and loose rocks make that section unsafe.
