Dartrey Forest, near Rockcorry in north-west County Monaghan, Ireland, was formerly part of the Dartrey Estate, located in the Barony of Dartrey. It was also named "Dawson Grove", the country estate of the Dawson family, who had the title "Earl of Dartrey" from 1866 to 1933. The once vast estate was centred on Dartrey Castle (demolished in 1946). The forest's main gate is only a few miles from Cootehill. It is currently managed by Coillte as a commercial forest. The Forest is partially bordered by what is known locally as 'the Famine Wall', which stretches halfway along the road from Cootehill to Rockcorry (the R188).
