Vieraella is an extinct genus of frog from the Jurassic period. It was about 3 cm long.
Vieraella was the first true frog, as the older Palaeobatrachus still featured many primitive characteristics. Its anatomy was highly similar to that of modern frogs. Vieraella belongs to the still existing tailed frog family.
