The Ladinian is a stage and age in the Middle Triassic series or epoch.

[8] The Ladinian was preceded by the Anisian and succeeded by the Carnian (part of the Upper or Late Triassic).

Its name comes from the Ladin people that live in the Italian Alps (in the Dolomites, then part of Austria-Hungary).

[10] The top of the Ladinian (the base of the Carnian) is at the first appearance of ammonite species Daxatina canadensis.

The Ladinian is sometimes subdivided into two subages or substages, the Fassanian (early or lower) and the Longobardian (late or upper).
