Yuri Alexandrovich Bezmenov (Russian: Ю́рий Алекса́ндрович Безме́нов; December 11, 1939 – January 5, 1993; alias: Tomas David Schuman) was a Soviet journalist for Novosti Press Agency (APN). In 1970, as a member of the Soviet mission in New Delhi, India, Bezmenov defected to the West and was re-settled in Canada pursuant to an arrangement between American and Canadian security agencies.

Bezmenov is best remembered for his anti-Marxist, anti-Soviet, and anti-atheist lectures and books published in the 1980s.
