Little Cumbrae (Scottish Gaelic: Cumaradh Beag) is an island in the Firth of Clyde, in North Ayrshire, Scotland.

The Cumbraes take their name from the Old Norse Kumreyjar, meaning "islands of the Cymry" (referring to the Cumbric-speaking inhabitants of southern Scotland).

Today the island's main settlement is at Little Cumbrae House on the eastern shore, facing the Scottish mainland.

A later northwest–southeast aligned swarm of dykes of Palaeogene age intrude these rocks whilst several geological faults run generally NW-SE.

A raised beach is developed along the lower-lying east coast of the island on which have accumulated marine deposits and blown sand.

[16] His son, Robert II spent time there hunting the deer, however the site of the "Auld Castle" is unknown.

In the early 20th century, under the ownership of Evelyn Stuart Parker, a new 'mansion house' was created from the original single storey farmhouse, the gardens were laid out to a plan by Gertrude Jekyll, the renowned garden designer, and substantial repairs were undertaken to the castle and the original lighthouse.

[20] The traditional Cumbrae Lighthouse was designed and built in 1793 by Thomas Smith under commission from the Commissioners of the Northern Lights.

The lighthouse lies on a broad raised beach on the western shore of the island looking out into the Firth, 0.5 km from the first light.

Little Cumbrae was privately purchased in 2003 and there were plans for its development as a memorial park, nature reserve and corporate escape.
