Caherconnell Stone Fort (Cathair Chonaill) is a well-preserved medieval stone ringfort in the Burren, County Clare, Ireland. It sits about 1 km south of the Poulnabrone dolmen, just west of the R480 road between Ballyvaughan and Leamaneh Castle, in the Caherconnell townland, Kilcorney parish.

The fort forms a circular enclosure with a diameter of 42 meters. The walls are made of local limestone, up to 3 meters thick and about 3 meters high, with the original height likely a bit higher. The entrance is on the eastern side. Inside, there is a roughly 1-meter-wide dividing wall and two visible structures.

Structure A lies near the north wall and measures about 10 by 5 meters. Structure B sits by the west wall, about 7.5 by 5 meters, with its north wall forming part of the dividing wall. There are additional surrounding structures, and a souterrain has been suggested but nothing definite has been found.

Caherconnell is similar in style to nearby cashels such as Cahermore and Cahermacnaghten, which stayed in use for a long time. Radiocarbon dating shows the ringfort was mainly built from the early 10th to the mid-12th century and used into the early 13th century. A later rectangular phase (Structure A) was probably added between the early 15th and mid-17th century. It isn’t certain whether the site was continuously inhabited in the 14th century.

Findings indicate the inhabitants produced high-status items locally, including pin-making, and there is evidence of ironworking and metal work. The fort’s size and walls make it stand out among Burren cashels.

In the 15th and 16th centuries, inhabitants were Gaelic and not from the main O’Loghlen family branch that had moved to Glensleade Castle nearby. Postholes of an older Neolithic or Bronze Age timber structure were found to the southwest, near a later stone building. This may have been a medieval corn-drying kiln, but three people were found at its entrance dating to the 15th–16th century, which remains mysterious.

Today, Caherconnell is open to the public. The owner runs a visitor centre with an audio-visual presentation and a café. Since 2010, an archaeological field school has operated on-site, offering hands-on learning with top archaeologists.
