The Ladinian is a stage and age in the Middle Triassic series or epoch. It spans the time between 242 Ma and ~237 Ma (million years ago).^[8] The Ladinian was preceded by the Anisian and succeeded by the Carnian (part of the Upper or Late Triassic).^[9]

The Ladinian is coeval with the Falangian regional stage used in China.
