Louis-Charles Caigniez (13 April 1762 – 19 February 1842) was a 19th-century French playwright.
Endowed with a real talent for the stage, Caigniez competed on the boulevard theaters with René Charles Guilbert de Pixérécourt and was nicknamed "the Racine of melodrama", of which Pixérécourt was called the Corneille.
Caigniez literary taste was enough to succeed in more delicate works. His three-act comedy Volage presented in 1807 at the Théâtre Louvois and his Méprise en diligence, another three-act comedy given at the Théâtre Favart in 1819, are notable by their original and comic situations.
The main success of this author in the melodrama genre are: le Jugement de Salomon (1802) and la Pie voleuse, ou la Servante de Palaiseau (1815). These two plays were presented with the same long success, both in Paris and in the cities of the province and abroad ; Rossini composed his opera La gazza ladra after the second.
