袋獅（Thylacoleo carnifex）曾經係最大隻嘅食肉有袋動物，但已經絕種。佢哋喺上新世末期至更新世末嘅澳洲生存。模式種叫劊子手袋獅（T. carnifex）。

描述

袋獅可能喺森林、林地、灌叢帶同埋河谷濕地等地獵食。

袋獅嘅近親係食齋嘅袋熊同樹熊。佢係所有現存同已絕種嘅哺乳動物中，咬合力最勁嘅，重100公斤嘅袋獅一咬可以媲美一隻重250公斤嘅獅子^[1]。佢會獵食好似雙門齒獸及巨型短面袋鼠等大型動物。佢係有袋類中專門嘅獵食者^[2]，佢嘅前肢極之強壯，有可收縮嘅爪，呢啲都係有袋類中未有過。佢有鋒利嘅裂齒同強壯嘅顎肌，可以喺獵物度撕開一大片嘅肉。呢啲特徵綜合起來估計佢好似豹咁樣，可能有能力爬樹，同保存獵物嘅腐肉。

袋獅膊頭離地75厘米，長1.5米。佢哋平均重101-130公斤，個別嘅可重達124-160公斤^[3]。體型差唔多同雌獅，老虎咁上下。

化石

袋獅嘅化石喺澳洲多個位點都有發現。2007年，喺納拉伯平原下嘅山窿就發現咗成副袋獅嘅骨同頭骨，估計佢係喺平原罅跌死嘅。^[4]另外，亦發現咗一頭幼獅喺其母獅育幼袋中嘅化石。
