Abiria was a region of India described by Classical authors, mainly Ptolemy. It covers the area east of the Indus River Delta and is apparently named for the Abhira peoples, presumably in residence of the region.
"Beyond the gulf of Baraca is that of Barygaza and the coast of the country of Ariaca, which is the beginning of the Kingdom of Nambanus and of all India. That part of it lying inland and adjoining Scythia is called Abiria, but the coast is called Syrastrene." Periplus, Chap. 41 1
