The 1977 Moscow bombings were a series of three terrorist bombings in Moscow on 8 January 1977. The attacks killed seven people and seriously injured 37 others. No one claimed responsibility for the bombings, although three members of an Armenian nationalist organization were executed early in 1979 after a KGB investigation and a secret trial. Some Soviet dissidents said that the suspects had an alibi. Soon after the event Andrei Sakharov issued a public appeal, expressing concern that the bombings might "be a new provocation on the part of the organs of repression". According to historian Jay Bergman, "who actually caused the explosion has never been determined conclusively".

Stepan Seghbosi Zatikyan was a Soviet dissident and one of the founders of the Armenian NUP.
