The 3/40 Evzone Regiment () or 40th Regiment (40° Σύνταγμα) was an elite regiment of Evzones of the Hellenic Army, recruited in Epirus and headquartered in Arta. It was formed in 1913 after the Balkan Wars. In 1920, it was the first Greek unit to enter Adrianople, the capital of Eastern Thrace which had been ceded to Greece by the Treaty of Sèvres. Upon the outbreak of the Greco-Italian War, the unit had just come under the command of Col. Thrasyvoulos Tsakalotos, and was among the first to face the Italian attack.
