Ben Crom (from Irish Binn Chrom, meaning 'curved/stooped peak') is a 526 metres (1,726 ft) mountain in the Mourne Mountains in County Down, Northern Ireland.

[1][2] An exposed area on the south west of the mountain shows where the Eocene aplitic granite meets the laccolith top of the older Mesozoic granite ring dike.

The summit of the mountain features granite crags which are crossed by basic and feldspar porphyry dikes.

The mountain is used for sheep grazing and hill walking.
