The 3rd Greek Mountain Brigade (, Triti Elliniki Οrini Τaxiarkhia, ΙΙΙ Ε.Ο.Τ.) was a unit of mountain infantry formed by the Greek government in exile in Egypt during World War II. It was formed from a few thousand politically reliable loyalists, and was briefly trained in Lebanon before being dispatched to Italy. Commanded by Colonel Thrasyvoulos Tsakalotos, it fought in the Battle of Rimini in Italy (under I Canadian Corps), where it earned the honorific title "Rimini Brigade" (Ταξιαρχία Ρίμινι Τaxiarkhia Rimini).
