Robert Bernardis (7 August 1908 – 8 August 1944) was a German army officer and Austrian resistance fighter involved in the attempt to kill Nazi Germany's dictator Adolf Hitler in the 20 July Plot in 1944.

However, once the Second World War had begun, experiences at the front such as witnessing the murder of civilians changed his mind and he became involved in the resistance movement against the Third Reich.

He was not stationed near Hitler's headquarters at Wolfsschanze near Rastenburg when the 20 July assassination attempt was carried out, but was in Berlin instead.

Unaware that the bomb had failed to kill Hitler, Bernardis was responsible for the order that set Operation Valkyrie in motion.

On 8 August, he was sentenced to death by the German "People's Court" (Volksgerichtshof) and executed the same day.
