Ernest Cœurderoy, (born at 22 January 1825 at Avallon (Yonne), died at 21 October 1862 at Geneva was a medical doctor, a revolutionary journalist and a French libertarian writer.
He lived in exile for most of his life and committed suicide.
He participated in the French Revolution of 1848 and was devastated by its defeat.
Coeurderoy vigorously opposed the republican and socialist leaders, who saw them as responsible for the defeat of the 1848 revolution.
Under the triple influence of Charles Fourier, Pierre Leroux and Proudhon, he advocated for a system that was a "synthesis of collectivism and libertarian mutualism".
He demanded collective ownership of the means of production, free access for all to work instruments, individual property and the mutual exchange of labor products.
