Drastamat Kanayan, better known as Dro (Դրո), was an Armenian military commander and politician. He was a member of the Armenian Revolutionary Federation. He briefly served as Defence Minister of the First Republic of Armenia in 1920, during the country's brief independence. During World War II, he led the Armenian Legion, which consisted of Armenian POWs who opted to fight for Nazi Germany rather than face the brutal conditions of the Nazis' camps.

The First Republic of Armenia, officially known at the time of its existence as the Republic of Armenia, was an independent Armenian state that existed from May 1918 to 2 December 1920 in the Armenian-populated territories of the former Russian Empire known as Eastern or Russian Armenia. The republic was established in May 1918, with its capital in the city of Yerevan, after the dissolution of the short-lived Transcaucasian Democratic Federative Republic. It was the first Armenian state since the Middle Ages.
