Lithodryas is a prehistoric genus of butterfly in the family Lycaenidae. It was introduced as a replacement for Samuel Hubbard Scudder's genus Lithopsyche which is invalid as a homonym, as another fossil lepidopteran genus had been described under the same name shortly before Scudder established his genus.

The type species was found in Tertiary deposits at Florissant.

In The Land Before Time

A pair of Lithodryas are briefly seen in The Land Before Time II: The Great Valley Adventure. When the pair fly by Chomper, the young Sharptooth attempts to eat one of them when it lands on a nearby plant. Fortunately for the insect, it is able to escape, and rejoins its partner. The two are last seen flying together over a hill.
