Vyacheslav Mikhalovich Gaizer (ru|Вячеслав Михайлович Гайзер, kv|Гайзер Миш Вечӧ, Gajźer Miš Većö), born in 1966, is a Russian politician who served as Head of the Komi Republic from January 2010 to September 2015.
On 19 September 2015, an investigation by Russia's Investigative Committee has led to his arrest. Gayzer and 18 of his associates, some of them also members of the regional administration, have been charged with organizing and running a criminal gang involved in the theft of state property on a mass scale. The charges against him were dropped in March 2017.[1]
