Richard Bienert (September 5, 1881 – February 2, 1949) was a Czech high-ranking police officer and politician.
During World War I Bienert cooperated closely with the Czech resistance movement and after the proclamation of Czechoslovak independence in October 1918 he was rewarded with an appointment to the position of Prague Police Director.
In 1945 Bienert replaced Krejčí in this position and at the same time also served as the substitute for seriously ill president Hácha.
However the same morning the Prague uprising broke out and Bienert was captured by insurgents in the broadcasting room of City Hall.
After the end of World War II, Bienert was tried for treason and collaboration with the Nazis, but because of many mitigating circumstances he was sentenced to only three years in prison.
