Alexander Nikolaevich Buinov (Russian: Александр Николаевич Буйнов, born 24 March 1950) is a Russian singer, songwriter and keyboardist. He is best known for his tenure with Vesyolye Rebyata between 1973 and 1989, before starting his solo career.

In the English-speaking world, he is known for his song "VDV – z neba privet" (VDV: Greetings from the Sky), which sings the praises of the Russian Airborne Troops, or VDV ("Vozdushno-desantnye voyska Rossii"; Russian script: Воздушно-десантные войска России, ВДВ; "Air-landing Forces"), a military branch of the Armed Forces of the Russian Federation. A number of parody videos have surfaced on the Internet with the apparent music of his VDV – s neba privet, but subtitled with English lyrics mocking Russia.

Buinov is a member of the Russian Political Party United Russia. Buinov was included on a 2019 list of blacklisted people banned from performing in Ukraine due to his links to the Putin government. In 2020, during the protests following the Belarusian presidential elections, Buinov recorded a song in support of Alexander Lukashenko called "Artists for Peace – Don’t Give Away Your Loved One", though his representative subsequently stated that Buinov had not known that the lyrics of the song supported Lukashenko.
