Augustin Bon Joseph de Robespierre (21 January 1763 – 28 July 1794) is the younger brother of French Revolutionary leader, Maximilien Robespierre.

He was born in Arras, the youngest of five children of the lawyer Maximilien-Barthelemy-François de Robespierre, and Jacqueline-Marguerite Carraut, the daughter of a brewer.

His mother dies when he is one-year old, and his grief-stricken father abandons the family to go to Bavaria, where he dies in 1777.

He is brought up by an aunt and trained as a lawyer.

Like his brother, he is a radical during the Revolution.
