Binn idir an dá Log, Mountain summit in County Galway, Ireland

Binn idir an dá Log is the highest mountain of the Maumturk range in Connemara, County Galway, rising to 702 metres. Its high, winding summit ridge is littered with quartzite rocks and gravel, and includes the subsidiary peak Binn idir an dá Log SE Top at 659 metres. Two glacial corries bound the ridge, the north-western one holding a lake.

Binn idir an dá Log takes its Irish name, "peak between the two hollows", from the two glacial corries at each end of its summit ridge; the north-western one holds a lake, Lough Maumahoge. The ridge is littered with quartzite rock and gravel, and the col to the north-west is the pass of Maumahoge. The Placenames Database of Ireland records the anglicised form Benadolug, which other Irish mountain placename guides do not list.

Since 1975, University College Galway Mountaineering Club organizes an annual challenge walk across the Maumturks range, incorporating checkpoints at this summit.

Multiple routes lead to the summit, with one popular path taking about 6 kilometers through Maumahoge pass. An alternative approach starts from Maumeen col, allowing climbers to choose based on their experience and preferences.

Binn idir an dá Log is the highest Maumturk peak, and its 644 m prominence makes it a P600 and a Marilyn; on the MountainViews list of Ireland's 100 highest mountains it ranks 52nd. Its name means "peak between the two hollows", after the two glacial corries at each end of the ridge.
