The Vacomagi were a people of ancient Britain, known only from a single mention of them by the geographer Ptolemy c. 150. From his general description and the approximate locations of their neighbors, their territory was the region of Strathspey, including that part of the northern coast of Scotland. Ptolemy says that their towns or principal places were called 'Bannatia', 'Tamia', Pinnata Castra, and 'Tuesis'.
