Jean Baptiste Tardieu (1768 - December 24, 1837) was a French cartographic engraver of the large Paris-based Tardieu family. The Tardieu family was extremely prolific, with numerous members, for over 200 years, being skilled and active engravers. Most of the Tardieu engravers simply identified themselves as 'Tardieu' or at best with their initials, so it is often extremely difficult to distinguish their individual work. Along with fellow engraver Louis Tardieu (1765 - 1793), Jean Baptiste was the son of the engraver Pierre Joseph Tardieu (1724 – 1793) and Henriette Larchange (1735 – 17??), Pierre Joseph's second wife. From Pierre Joseph's first wife, Anne Catherine Labdouche (1725 – 1758), he also had a half-sister, Rosalie Tardieu (c. 1750 – 1756), and four half-brothers, all also engravers: Jean Baptiste Pierre Tardieu (1746 – 1816), Jean Claude Tardieu (1746 – 1828), Pierre Alexandre Tardieu (1756 – 1844), and Antoine-François Tardieu (1757 – 1822).
