Binnein an Fhidhleir, is one of the Arrochar Alps, a mountain in Argyll and Bute, western Scotland. Located in the Loch Lomond and The Trossachs National Park.

Located above the Butter Bridge, on the north side the A83 road, facing Beinn an Lochain to the south. The mountain has several tops, including; Creag Bhrosgan 711 metres (2,333 ft); Stob Coire Creagach, which replaced Binnein an Fhidhleir as the Marilyn in April 2006, at 817 metres (2,680 ft). One without any name at all at 748 metres (2,454 ft). Binnein an Fhidhleir itself, further to the west at 811 metres (2,661 ft). Although Stob Coire Creagach is the highest summit, the name Binnein an Fhidhleir is generally used for the whole mountain. The shortest route of ascent is directly up the hillside above Butter Bridge, where there is a carpark. A number of small crags must be avoided, and the route is steep and unrelenting. Alternatively, the mountain can be ascended from further up Glen Kinglas by way of Binnein an Fhidhleir's northern ridge: although longer this route is considerably less steep.
