Deinococcota (synonym, "Deinococcus-Thermus") is a phylum of bacteria with a single class, Deinococci (from Ancient Greek δεινός (deinós), meaning "terrible", and κόκκος (kókkos), meaning "berry"), that are highly resistant to environmental hazards, also known as extremophiles.

These bacteria have thick cell walls that give them gram-positive stains, but they include a second membrane and so are closer in structure to those of gram-negative bacteria.
