The Callanish Stones (or "Callanish I"), Clachan Chalanais or Tursachan Chalanais in Gaelic, are situated near the village of Callanish (Gaelic: Calanais) on the west coast of the isle of Lewis, in the Outer Hebrides (Western Isles), Scotland.

Construction of the site took place between 2900 and 2600 BC, though there were possibly earlier buildings before 3000 BC. A tomb was later built into the site. Debris from the destruction of the tomb suggests the site was out of use between 2000 BC and 1700 BC. The 13 primary stones form a circle about 13 m in diameter, with a long approach avenue of stones to the north, and shorter stone rows to the east, south, and west (possibly incomplete avenues). The overall layout of the monument recalls a distorted Celtic cross. The individual stones vary from around 1 m to 5 m in height, with an average of 4 m, and are of the local Lewisian gneiss.

The tallest of the stones marks the entrance to a burial cairn where human remains have been discovered. An excavation campaign in 1980 and 1981 showed that the burial chamber was a late addition to the site, and that it had been modified a number of times.
