Machrie Moor Stone Circles is the collective name for six stone circles visible on Machrie Moor near the settlement of Machrie on the Isle of Arran in Scotland. Six stone circles are visible on the moor immediately east of the derelict Moss Farm. Some circles are formed of granite boulders, while others are built of tall red sandstone pillars. The moor is covered with other prehistoric remains, including standing stones, burial cairns and cists. Several hut circles can also be seen as low rings of turf-covered stone.

The six stone circles are situated below a prominent notch on the skyline to the northeast where Machrie Glen divides into two steep-sided valleys. At the summer solstice the notch is intersected by the sun at sunrise, and this may explain why the circles were sited in this location.
