Mister X are a Belarusian street punk band formed in Grodno, West Belarus, in 2003 by Igor Bancer and Boris of Oi!

[1] As a group they claim to be apolitical and the lyrics of their songs are generally quite subcultural in nature – about having fun, being honest and living life accordingly to your ideals – but all members are committed to anti-fascism and some of them take part in various sports or anarchist initiatives during their free time.

[15] Although Mister X's self-proclaimed apolitical stance initially led to them being somewhat ostracised on the then highly politicised Belarusian punk scene, it has not stopped them from garnering an international following of fans in the years following the band's creation,[16] despite difficulties with the country's regime and travelling.

[17] One of their gigs in Ryazan was broken up by the Russian law enforcement under false accusation of drug use, which later lead to several cases of police brutality and torture on numerous members of the audience.

[22][23] In June 2021, due to Igor being sentenced to 1.5 years of penal labour in a correctional facility for protesting, the band was forced to temporarily put its on activity on hold.
