The Ardlair Stone is a class I Pictish stone that stands in a field in Ardlair, Kennethmont, Aberdeenshire, Scotland.

It is associated with a number of other stones that have been proposed by some to be the remains of a recumbent stone circle.

A rough hewn stone of grey Gneiss, the stone was identified as Pictish in 1901.

[1] The stone bears the incised symbols of the Pictish beast, the tuning fork and the mirror.
