Charles Humbert (28 May 1866, Loison, Meuse – 1 November 1927) was a French army captain, tax collector, Senator and newspaper proprietor.

He played an important part in the series of inquiries instigated by General André into the religious and political views of officers.

[1] After two years he resigned owing to the controversy caused by his opposition to Freemasonry in the army, and became a tax collector.

Before World War I he wrote much on military subjects, and made speeches criticising the inadequacy of the defences of the French Army, and the insufficiency of officers and munitions.

Humbert and his wife divorced in 1908, and he then married Marie Levylier (née Nathan, 1872–1920).
