August Jean-Marie Vermorel (June 21, 1841 - June 20, 1871) was a French journalist.
He was born at Denice.
A radical and socialist, he was attached to the staff of the Presse (1864) and the Liberte (1866). In the latter year he was appointed editor of the Courrier Français, and his attacks on the government in that organ led to his imprisonment. In 1869 he was editor of the Reforme, and was again imprisoned for denouncing the government.
On the overthrow of the Second Empire in 1870 he was released and took an active part in the Commune. He was dangerously wounded while fighting at the barricades, taken prisoner and removed to Versailles, where he died.
