'''Uricite''' is a rare organic mineral form of uric acid, C<sub>5</sub>H<sub>4</sub>N<sub>4</sub>O<sub>3</sub>. It is a soft yellowish white mineral which crystallizes in the monoclinic system.

==Discovery and occurrence== It was first described in 1973 for an occurrence in bat guano in Dingo Donga Cave, Eucla, Western Australia.<ref name=Mindat/> The name is for its composition, anhydrous uric acid. It occurs with biphosphammite, brushite and syngenite at the type locality in Dingo Donga Cave.<ref name=HBM/>
