Vitaly Kasko (Ukrainian: Віталій Вікторович Касько; born 29 June 1976) is a Ukrainian lawyer. He served as Deputy Prosecutor General under Viktor Shokin and resigned on February 15th denouncing the corruption and "total lawlessness" of the Prosecutor's office. In late March, just before Shokin's dismissal, Kasko was accused of a fraud case and saw later his apartment seized under what he claims was a revenge for his criticism.
Late April 2016 Kasko was board member of Transparency International Ukraine.
