Vopli Vidopliassova (Ukrainian: Воплі Відоплясова [ˈwɔpl⁽ʲ⁾i widoˈplʲɑsowɐ], lit. 'Screams of Vidoplyasov'), also shortened to VV (ВВ), is a Ukrainian rock band, founded in 1986 in Kyiv. The leader of the band is singer Oleh Skrypka. Vopli Vidopliasova are the founders of Ukrainian rock-n-roll style and neo-ethnic rock. They first sang Ukrainian rock outside Ukraine. Their influences include folk, patriotic songs, punk, hard rock, heavy metal and, most recently, electronic music.

Their song Den Narodzhennia is featured in the Russian crime films Brother and Brother 2 by director Aleksei Balabanov. Band member Oleh Skrypka has also produced several solo albums.

In 2009, their record label, Kraina Mriy, released all their albums for free as a Christmas present.

Much of their early material (1986-1996) is in Drop C tuning.
