盖乌斯·撒路斯提乌斯·克里斯普斯（拉丁语：Gaius Sallustius Crispus，常简称为撒路斯提乌斯，或据英文Sallust译为萨卢斯特，前86年－前34年），古罗马著名历史学家。主要作品有《喀提林阴谋》（Conspiracy of Catiline）、《朱古达战争》（Jugurthine War）等。

Gaius Sallustius Crispus, usually anglicised as Sallust (/ˈsæləst/; 86 – c. 35 BC), was a Roman historian, politician, and novus homo from a provincial plebeian family. Sallust was born at Amiternum in the country of the Sabines and was a popularis, an opponent of the old Roman aristocracy, throughout his career, and later a partisan of Julius Caesar. Sallust is the earliest known Roman historian with surviving works to his name, of which Catiline's War (about the conspiracy in 63 BC of L. Sergius Catilina), The Jugurthine War (about Rome's war against the Numidians from 111 to 105 BC), and the Histories (of which only fragments survive) are still extant. Sallust was primarily influenced by the Greek historian Thucydides and amassed great (and ill-gotten) wealth from his governorship of Africa.
