失窃的一代（英语：Stolen Generations，亦作Stolen generation、Stolen children），又翻译为失窃一代、被偷走的一代、被偷走一代、被偷的一代、被偷一代、被窃的一代、被窃一代，是指澳大利亚政府于1909年至1969年年间（部份地方持续至1970年代）所实行的「同化政策」所影响的一代人。当年政府认为澳洲原住民「低贱无知」及「将会消失」，因此强行将10万名澳洲原住民儿童永久性地带往白人家庭或者政府机构照顾，以「白化」原居民，令到澳洲原住民儿童与父母长期分离。加上当时多数白人家庭歧视澳洲原住民，往往虐打他们及迫使他们忘记其语言和文化。他们被逼学习白人的语言和生活方式，甚至乎被性侵犯、及缺乏接受正当教育的机会，令大部份澳洲原住民在心理及身理上均受到伤害 。

The Stolen Generations (also known as Stolen Children) were the mixed-race children of Australian Aboriginal and Torres Strait Islander descent who were removed from their families by the Australian Federal and State government agencies and church missions, under acts of their respective parliaments. The removals of those referred to as "half-caste" children were conducted in the period between approximately 1905 and 1969, although in some places mixed-race children were still being taken into the 1970s. Documentary evidence, such as newspaper articles and reports to parliamentary committees, suggest a range of rationales. Motivations evident include child protection, beliefs that given the Aboriginal people would die out, given their catastrophic population decline after white contact, and the belief that full-blooded Aboriginal people resented miscegenation and the mixed-race children fathered and abandoned by white men.
