The Trimeticcia di Segezia is a modern breed of domestic sheep from Puglia in southern Italy.
[3]: 292 [2] It is named for the town of Segezia, a frazione of Foggia, where it was created at the Istituto Sperimentale per la Zootecnia, an experimental breeding station of the Ministero delle Politiche Agricole, Alimentari e Forestali, the Italian ministry of agriculture.
[3]: 292 "Trimeticcia" means "three-way hybrid": the breed was created by cross-breeding Gentile di Puglia ewes with French Île-de-France rams, and then crossing the resultant hybrid with Württemberger rams; the resulting stock was selectively bred for adaptation to the climate and conditions of the area.

[3]: 292 The Trimeticcia di Segezia is one of the forty-two autochthonous local sheep breeds of limited distribution for which a herd-book is kept by the Associazione Nazionale della Pastorizia, the Italian national association of sheep-breeders.
