Eobacterium is a fossil genus of probable[2] bacteria from the Fig Tree Formation in South Africa.[3][4] It lived during the Paleoarchean era, around 3.277–3.225 Ga, making it one of the oldest known organisms if it is valid.[1][3] The discovery of Eobacterium and other Fig Tree organisms such as Archaeosphaeroides in the 1960s helped prove that life existed over three billion years ago.[4]

The genus is monospecific, and contains one species, Eobacterium isolatum.[5]
