Édouard-André Barnard (September 30, 1835 – August 19, 1898) was a Lower Canada born militia officer.

His father was Edward Barnard, a politician from Trois-Rivières.

Barnard eventually gravitated toward a career in the militia.

By 1867, now a major, he offered his services to Bishop Ignace Bourget and put together a force to assist Pope Pius IX in defending against attacks on the Papal State by Giuseppe Garibaldi.

The defenses were successful, but many questioned his motives, and he soon returned to farming.
