Jura iku périodhe utama sajeroning skala wektu géologi kang dumadi watara 199,6 ± 0,6 tekan 145,4 ± 4,0 yuta taun kapungkur, sawisé périodhe Trias lan ndhisiki périodhe Kapur. Lapisan batuan kang awèh ciri awal lan akir périodhe iki kaidhèntifikasi kanthi becik, nanging wektu pasé ora bisa dipesthèkaké watara 5 nganti 10 yuta taun. Jura wujud périodhe patengahan éra Mesozoikum, kang ditepungi uga minangka "Jaman Dinosaurus". Awal périodhe iki ditengeri kanthi prastawa curesé Trias-Jura.
Jeneng périodhe iki diwènèhaké déning Alexandre Brogniart dhedhasar akèhé watu kapur laut kang tinemu ing Pagunungan Jura, ing laladan patemon Jerman, Prancis, lan Switserlan.
