尤利卡起事（英语：Eureka Rebellion）发生在1854年，是一场由澳洲巴拉瑞特的金矿矿工发起的武装起事，他们反抗英国的殖民当局。尤利卡堡垒营战役（英语：Eureka Stockade）是这场起事的通称。该战役是矿工与澳洲各殖民地部队之间于1854年12月3日在尤利卡的战斗。该战役之命名是于自矿工在冲突中树立的木制围墙。这场起事导致27人死亡，多数是叛乱者。

这件事是巴拉瑞特地区****之高峰，当时正值维多利亚淘金潮，矿工反对采矿牌照的费用，认为采矿牌照是无代表征税；又对政府、警察以及军队的行为有所异议。这场本土起事从巴拉瑞特改革联盟运动成长而来，最终矿工树立了一座粗糙的堡垒营，殖民地部队在两日后午夜围攻他们，行动迅速而致命。

The Battle of the Eureka Stockade, by which the rebellion is popularly known, was fought between miners and the Colonial forces of Australia on 3 December 1854 at Eureka Lead and named for the stockade structure erected by miners during the conflict. The rebellion lasted for less than half an hour and resulted in the deaths of at least 27 people, the majority of whom were rebels.
