Claraia is an extinct genus of scallop-like bivalve molluscs that lived from the Capitanian stage of the Middle Permian to the Anisian stage of the Middle Triassic, 266-237 million years ago.

Fossils have been found worldwide in North America, Europe, Asia, Africa, and Australia.

These are common fossils subsequent to the Permian-Triassic boundary, suggesting that the genus experienced rapid diversification during and after the Permian–Triassic extinction event, around 251.9 million years ago, making it a Disaster taxon Claraia may have been an opportunistic genus that filled the niche of many benthic invertebrates such as brachiopods that were heavily impacted by the extinction.

A narrowing of the byssal notch and a trend towards a smoother shell in species of Claraia over time may have led to increased mobility.
