The Amazon Milk Frogs (Trachycephalus resinifictrix) is a large species of arboreal frog native to South America. It is sometimes referred to as the Mission Golden-eyed Tree Frog or Blue Milk Frog. It was first discovered along the Maracanã River, in Brazil.

The "milk" in the name comes from the milky colored fluid these frogs excrete when stressed.

Amazon Milk Frogs inhabit humid rainforest regions. They often inhabit vegetation which extends over permanent, slow moving water sources. Like most other species of frog, Amazon milk frogs are insectivorous. They will consume almost any type of small arthropod they can overpower and swallow.

Trachycephalus resinifictrix is commonly found in captivity. They are a species of moderate difficulty to care for, requiring a significant amount of space, humidity (this can be achieved via a water area and misting once or twice daily) and regular cage maintenance to ensure a clean healthy environment.
