Leptoxis compacta, the oblong rocksnail, is a species of freshwater snail with an operculum, an aquatic gastropod mollusk in the family Pleuroceridae.

This species is endemic to the Cahaba River in Alabama, United States. It was thought to be extinct due to habitat loss since it had not been collected since 1933,[3] and was formally declared extinct in 2000.[4] The IUCN Red List had previously listed it as critically endangered in 1996 but there was no survey data available at that time.[4] It was rediscovered in a small section of its previously described habitat in the Cahaba River in 2011, with a formal report published in August 2012.[3][5]

Molecular systematic analyses are underway to clarify the genetic position of Leptoxis compacta.[3]
