The Jonica is a breed of domestic goat from the province of Taranto, in Puglia in southern Italy. The origins of the breed are uncertain; it is thought to have originated from the crossing of local varieties with the Maltese breed. The Jonica is one of the eight autochthonous Italian goat breeds for which a genealogical herdbook is kept by the Associazione Nazionale della Pastorizia, the Italian national association of sheep-breeders.
At the end of 2013, the registered population was 232.
