The 3rd Mechanized Infantry Brigade "RIMINI" (3η Μηχανοκίνητη Ταξιαρχία «ΡΙΜΙΝΙ») is a mechanized infantry brigade of the Hellenic Army based at Kavyli, Orestiada.

The brigade was established on 1885 at Trikala as a regiment[clarification needed] and took part in the Allied intervention in the Russian Civil War in the aftermath of World War I.

It also participated in the Asia Minor Campaign under the command of Nikolaos Plastiras.

The unit remains at Orestiada since 1977 as a regiment and after a Hellenic Army's wide re-organization became a brigade and took the honourable name 'Rimini', continuing the tradition of the 3rd Greek Mountain Brigade of World War II.
