Vasyl Virastyuk (Ukrainian: Василь Вірастюк; born 22 April 1974), is a Ukrainian former strongman competitor. He is a brother of Roman Virastyuk.
Vasyl Virastyuk competed in the finals of the World's Strongest Man contest in 2003 and 2004. He finished third in 2003 behind then-defending champion Mariusz Pudzianowski and runner-up Zydrunas Savickas. The following year Virastyuk won the 2004 World's Strongest Man title, placing ahead of Savickas and Pudzianowski (Pudzianowski would later be disqualified for testing positive for a banned substance).
After this victory there was a split in the world of Strongman competition. While some of the competitors such as Virastyuk and Zydrunas Savickas started competing for the IFSA Strongman title (with Savickas winning the title in 2005 and 2006), others such as Pudzianowski remained and competed for the Met-Rx World's Strongest Man title (with Pudzianowski winning in 2005, 2007, and 2008 Phil Pfister in 2006).
