Geofagi (græsk: geo- jord og fageia- spisning) er betegnelsen for en sygelig tendens til at spise jord, ler, kalk og aske.[1] En person som lider af geofagi kaldes en geofag.

Geofagi forekommer hos nogle dyr og kan være normal adfærd blandt disse. Geofagi optræder også hos mennesker, oftest i landdistrikter og i præ-industrisamfund og oftest hos børn og gravide kvinder.[2]:33 Geofagi hos mennesker er muligvis forbundet med spiseforstyrrelsen pica, der i Diagnostic and Statistical Manual of Mental Disorders (DSM) beskrives som en abnorm trang til at indtage ikke-nærende elementer.[3][4]
