Mount Moorosi (or Moorosi's Mountain) is a mountain in the Drakensberg mountain range on the banks of the Orange River in southern Lesotho.

It acquired the name Moorosi's Mountain after Moorosi, the Chief of a local tribe, who, after committing acts deemed to hostile to the Cape Colonial administration, fortified himself on the mountain.

A Royal Engineer who was posted to the mountain after the siege began stated that: "Moorosi's Mountain is an isolated kopje, rising steeply on the south bank of the Orange River, about 1,500 feet, and connected with the range on the south by a low narrow nek.

"[1] For actions during the siege three Victoria Crosses were awarded to British troops: Peter Brown, Edmund Hartley and Robert Scott.
