Six Kingdoms may refer to: In biology, a scheme of classifying organisms into six kingdoms: Proposed by Carl Woese et al.: Animalia, Plantae, Fungi, Protista, Archaea/Archaeabacteria, and Bacteria/Eubacteria; Proposed by Thomas Cavalier-Smith: Animalia, Plantae, Fungi, Chromista, Protozoa and Eukaryota
