The genus '''''Caladenia''''' belongs to the subfamily [[Orchidoideae]] of the orchid family ([[Orchidaceae]]). The abbreviation ''Calda.'' is often used in trade journals to indicate the genus.

The subtribe Caladeniinae is considered [[polyphyletic]], due to the alliance of ''Lyperanthus'' with the genera of ''Drakaeinae'' and ''Thelymitrinae''.
