The equites Dalmatae (Latin for "Dalmatian horsemen") were a class of cavalry in the Late Roman army. They were one of several categories of cavalry unit or vexillatio created between the 260s and 290s as part of a poorly understood reorganization and expansion of Roman cavalry forces. These new cavalry vexillationes, typically bearing the basic regimental designation equites, mostly originated as detachments of existing mounted units (alae, cohortes equitatae, equites legionis), which were separated from their parent corps and later constituted as independent units.
