The hierarchy of biological classification's eight major taxonomic ranks. Intermediate minor rankings are not shown.

The legion, in biological taxonomy, is a non-obligatory taxonomic rank within the Linnaean hierarchy which is subordinate to the class but superordinate to the cohort. It consists of a group of related orders and has been employed in some classifications of birds and mammals.

Legions may be grouped into superlegions or subdivided into sublegions, and these again into infralegions.^[1]
