Dockey Tarn is a small lake in South Lakeland district, Cumbria, England. It is located at a height of, on the west slope below the ridge from Nab Scar to Heron Pike, about south-east of Alcock Tarn, and about east of Grasmere.[1] It has been said to be one of the smallest tarns in the Lake District which is named on Ordnance Survey maps; it does not appear on their maps at 1:50,000 scale[2] but is marked and named on their 1:25,000 maps.[3]
A visitor in 2018 reported that the tarn had at that time dried up completely.[4]
The name of the tarn appeared in a 1749 document spelled "Dockrey Tarn", and is believed to derive from the local family surname Dockray.[5]
