  • 袋熊亞目 Vombatiformes


  • 袋貂亞目 Phalangeriformes


  • 袋鼠亞目 Macropodiformes




雙門齒目（学名：Diprotodontia）又稱袋鼠目，属脊索动物门哺乳纲，是一個包含約120種有袋類動物的目，其中有袋鼠、沙袋鼠、無尾熊與袋熊等。此外還有一些已滅絕的類群，如雙門齒科（Diprotodontidae）與袋獅科（Thylacoleonidae）。


雙門齒目中幾乎全部都是草食動物，少數屬於食蟲動物與雜食動物，不過這些食性可能是原來的草食者經過適應後的結果。雙門齒目生活於澳大利亞，已知最早的化石屬於漸新世。在大約5萬年前，早期人類到達澳大利亞之後，許多大型的雙門齒目逐漸滅絕。
