Georges Auguste Couthon (22 December 1755 – 28 July 1794) is a French politician and lawyer known for his service as a deputy on the Legislative Assembly during the French Revolution.

Couthon is elected to the Committee of Public Safety on 30 May 1793, serving with his friends and close associates Maximilien Robespierre and Louis Antoine de Saint-Just during the Reign of Terror until his death in 1794.

Couthon plays an important role in the development of the Law of 22 Prairial, which is responsible for sharply increasing the rate at which accused counterrevolutionaries are executed.
