小兔形袋狸（Macrotis leucura），又名小兔耳袋狸，是像兔的袋狸。牠们的大小如幼兔，生活在澳洲中部的沙漠。自1950年代起，相信牠们已经灭绝。

小兔形袋狸最先于1887年发现。牠们是杂食性的，主要吃白蚁、蚁及根。牠们呈灰褐色，下身呈浅灰色，尾巴白色。牠们比兔耳袋狸细小很多，只有300-450克重。牠们分布在澳洲中部的吉布生沙漠及大沙沙漠。牠们因被猎杀、被赤狐所掠食及与兔争夺食物下而灭绝。

小兔形袋狸会在砂堆中挖坑筑巢，深约2-3米，日间会以沙来屏蔽入口。牠们夜间活动，每季繁殖，每胎产两只袋狸。最后发现存活的小兔形袋狸是于1932年。最后捕获的标本是于1967年在楔尾鹰的巢中找到的头颅骨，估计牠死时约有15岁。

The lesser bilby (Macrotis leucura), also known as the yallara, the lesser rabbit-eared bandicoot or the white-tailed rabbit-eared bandicoot, was a rabbit-like marsupial. The species was first described by Oldfield Thomas as Peregale leucura in 1887 from a single specimen from a collection of mammals of the British Museum. Reaching the size of a young rabbit, this species lived in the deserts of Central Australia. Since the 1950s–1960s, it has been believed to be extinct.
