This list of the Cenozoic life of Washington contains the various prehistoric life-forms whose fossilized remains have been reported from within the US state of Washington and are between 66 million and 10,000 years of age. Significant biotas for the understanding of climate and biotic changes include the Ypresian Klondike Mountain Formation's paleobiota and the Barstovian Latah Formation's paleobiota.
