The Novantae were a people of the late 2nd century who lived in what is now Galloway and Carrick, in southwestern-most Scotland. They are mentioned briefly in Ptolemy's Geography (written c. 150), and there is no other historical record of them. Excavations at Rispain Camp, near Whithorn, show that it was a large fortified farmstead occupied between 100 BC and 200 AD, indicating that the people living in the area at that time were engaged in agriculture.
Their ethnic and cultural affinity is uncertain, with various authorities asserting Brythonic, Pict, Gael, or some combination thereof. However, the region has a history that includes all three as possibilities at various times, alone and in combination, and there is not enough information to disprove any of them.
