Sgurra Bhreac, Mountain summit in Cape Breton Island, Nova Scotia, Canada.

Sgurra Bhreac is a rock outcrop rising 50 m from the northern edge of The Big Barren, between the Breac Brook and Glengarry valleys on Cape Breton Island. Its summit reaches 222 m, the highest point on the island south of Bras d'Or Lake, about 30 km west of Sydney.

The mountain received its official name designation in December 1924 and was documented through geodetic survey markers installed before 1921. These markers were later upgraded in 1969, establishing this location as a registered geographic reference point in the region.

The name comes from Gaelic language traditions and refers to geographical features with spotted or marked characteristics found throughout Nova Scotia. This linguistic heritage reflects the Scottish roots that run deep in this region.

Hikers reach the summit through back roads such as Glengarry Road or unmarked trails near Rear Big Pond, about 30 kilometers west of Sydney. The route to the top is not always clearly marked, so visitors should be familiar with maps or GPS devices and prepared for variable ground conditions.

On the summit stand three survey markers: two brass or bronze disks and a copper bolt, established as a fourth-order station before 1921 and upgraded to first order in 1969/1970. The station carries Natural Resources Canada Geodetic Survey Division Unique Number 21139.
