大袋熊属(学名:Phascolonus)是生存于上新世[1]至更新世时期澳洲的大型袋熊,于1859年由理察·欧文发表命名。本属目前仅包含一种,即Phascolonus gigas,为目前已知体型最大的袋熊,体重可达200千克(440磅)[2]至360千克(790磅)[3]。大袋熊属与其他袋熊物种差异最大的特征在于其长板状的上门牙以及有明显向内凹陷的颅盖[3]。它们广泛分布于澳洲除西澳大利亚外的其他地区,偏好干燥或半干燥的内陆地区,以大量低营养价值的植物组织为食。虽然分布广泛,但推测大袋熊的生活环境仍然会选择于淡水水源附近为主[4]。大量的大袋熊化石遗骸发现于南澳大利亚的卡拉伯纳湖更新世年代的沉积物中[3]。和现存袋熊不同的是,大袋熊可能不具有挖掘地穴的能力[5]。大袋熊属约于50,000至40,000年前更新世晚期的第四纪灭绝事件与其他澳洲巨型动物群一同走向灭绝,推测是由于人类的到来[4][6]。支序分类学分析显示,大袋熊属与其他大型袋熊如拉氏袋熊属及Sedophascolomys为近亲[3]。
