Staphylococcus xylosus is a species of bacteria belonging to the genus Staphylococcus. It is a Gram-positive bacterium that forms clusters of cells. Like most staphylococcal species, it is coagulase-negative and exists as a commensal on the skin of humans and animals and in the environment.^[1]

Staphylococcus xylosus may be used as CNC (coagulase-negative cocci) in salami fermentation.^[2]

It appears to be far more common in animals than in humans. S. xylosus has very occasionally been identified as a cause of human infection, but in some cases it may have been misidentified.
