Eoborus is a fossil genus of medium-sized air-breathing land snails, terrestrial pulmonate gastropods in the family Strophocheilidae. Eoborus is the oldest fossil record of Strophocheilidae, dating from the Middle Paleocene of Brazil ()[1] and Uruguay (Santa Lucía Basin).[4] The Brazilian species, alongside from Uruguay, are the oldest fossil record of the family.[1]

The small size and large umbilicus of Eoborus are its most remarkable characteristics; it is considered primitive in the family Strophocheilidae.[1][3]

Some authors note that two other species, and could also belong to Eoborus.[3][4]
