András Tasnádi Nagy (29 January 1882 – 1 July 1956) was a Hungarian politician and jurist, who served as Minister of Justice between 1938 and 1939.

Tasnádi Nagy was elected to the Diet of Hungary in the colours of the governing Party of National Unity in 1935.

He became a leading member of the National Alliance of Lawmakers which was established by the Nazi-dominated puppet government.

As a result of this after the Second World War Tasnádi Nagy was arrested and sentenced to life imprisonment by the People's Tribunal in Budapest.

The first judgement was death, but Zoltán Tildy, the President of Hungary provided grace, so it was changed.
