Rabbs' Fringe-limbed Treefrog
Ecnomiohyla rabborum
- Critically endangered
- Card rarity: Legendary
- Amphibians

Ecnomiohyla rabborum, commonly known as Rabbs' fringe-limbed treefrog, is a possibly extinct species of frog in the family Hylidae. They are relatively large frogs that inhabited the forest canopies of central Panama. Like other members of the genus Ecnomiohyla, they are capable of gliding by spreading their enormous and fully webbed hands and feet during descent. The males of the species are highly territorial and would guard water-filled tree holes used for breeding. They were also the ones responsible for guarding and caring for the young, including providing food. They were the only known species of frog where the tadpoles derived nutrition by feeding on the skin cells of their fathers. It is also widely considered extinct, following the death of "Toughie", the last Rabbs' fringe-limbed treefrog.
