Olsenella porci is a species of Gram-positive short-rod-shaped, non-motile, obligately anaerobic bacterium in the family Atopobiaceae. It was isolated from the feces of a German Landrace pig (minipig breed) in Freising, Germany, and was validly published as a novel species in 2020.^[1]

The specific epithet porci is the Latin genitive of porcus (“pig”), indicating its porcine origin.^[1]
