Hovhannes Vasily Hakhverdyan (Armenian: Հովհաննես Հախվերդյան; Russian: Ованес Ахвердян) (29 June 1873 – 28 March 1931) was the first Minister of Defense of the First Republic of Armenia from 30 June 1918 to 27 March 1919.
Hovhannes Hakhverdyan was born in Saint Petersburg on 29 June 1873 in an Armenian noble family. His father, Vasily Fyodor Hakhverdov, was a Real State Councilor. He had two brothers, Major General Gavriil Hakhverdov and Lieutenant Colonel Georgiy Hakhverdov.
He graduated from the 1st Cadet Corps of Saint Peterburg in 1890, the 1st Military Pavlov School in 1892 and the Nikolaev Academy of Joint Staff in 1902.
Hakhverdyan participated in the Russian-Japanese War. He was appointed a Major General of the Russian Army on 22 October 1915. On 11 May 1916, he became head of Joint Staff of 120th Infantry Division.
After switching aliegence to the Republic of Armenia, Hakhverdyan was appointed Minister of Defense in the cabinet of Hovhannes Katchaznouni on 30 June 1918. He was not member of any political party and was supported by most of the powers as a professional and fair candidate for the Defense Minister position. Drastamat Kanayan was originally chosen to be the first Defence Minister, but had turned the position down. On 27 April 1919, Hakhverdyan left his position and Christophor Araratov became Defense Minister. Afterwards, he occupied the position of Head of Joint Staff. From 5 May 1920 to 25 November 1920, he was Vice-Minister of Defense.
During the Soviet invasion in December 1920, he was arrested with about 1,500 Armenia officers, including Tovmas Nazarbekian and Movses Silikyan. He later worked as a cashier. In 1930, he was arrested "for being a member of the counter-revolutionary monarchist officers' group, participating in the gatherings of the group, and having uncompromising attitudes toward the Soviet government". He was shot in Moscow on 28 March 1931. Hakhverdyan had been fully rehabilitated on 20 October 1989.
Hakhverdyan is the grandfather of famous Armenian bard Ruben Hakhverdyan.
