Tatyana Mikhailovna Lioznova (Russian: Татьяна Михайловна Лиознова; 20 July 1924 – 29 September 2011) was a Soviet film director and screenwriter best known for her TV series Seventeen Moments of Spring (1973).

Tatyana Lioznova was born in Moscow to parents Moses Alexandrovich (Russian: Моисей Александрович) and Ida Israilevna (Russian: Ида Израилевна). Her father worked as an economic engineer, but died in the early years of WWII, known in Russia as the Great Patriotic War. She was raised by her mother, who had a limited education, but worked hard to provide for her daughter.

Lioznova never had children of her own, but had an adopted daughter, Lyudmila Lisina.

In 2011, Lioznova died in Moscow, and is buried next to her mother in Moscow's Donskoye Cemetery.

Lioznova spent one semester at the Moscow Aviation Institute during the war, but ultimately decided on a different career path, and in 1943 began attending the Russian State University of Cinematography, the world's oldest film school, now known as the Gerasimov Institute of Cinematography. Lioznova was lucky enough to get into a workshop led by famed director Sergei Gerasimov and his wife, Soviet actress Tamara Makarova.

Following her graduation, Lioznova struggled to find work in the world of cinematography, and worked on custom sewing projects with her mother. She was able to find a job working as a handyman at a film studio, and worked in any position she was able to.

Her former mentor, Sergei Gerasimov, hired her as an assistant on several projects, and Lioznova spent eight years assisting other directors in their work before her own breakthrough.

Lioznova's breakthrough came in 1958, with the debut of her first film, Memory of the Heart.
