Stefania is a genus of frogs in the family Hemiphractidae. They are native to the highlands of the Guiana Shield in southern Venezuela, Guyana, and adjacent far northern Brazil.[1] Most are restricted to the tepui highlands, but S. evansi also occurs in lowlands. On most mountains there are only 1–2 species from this genus, but 5 are known from Mount Ayanganna and the neighbouring Mount Wokomung has 6 species. They are usually found near streams at low levels on branches/leaves or on the ground among vegetation/rocks.

They are famous for their breeding strategy where the development from eggs to froglets is completed on the back of the female (the eggs hatch to froglets; there is no free-swimming tadpole stage). The common name carrying frog is sometimes used for Stefania species and it refers to this behavior. A comparable behavior can also be seen in the other genera in the family Hemiphractidae.
