Paul Ėdouard Poincy (1833 – 1909) was an artist in New Orleans, Louisiana, United States who specialized in portrait, religious, landscape, and genre painting.

Paul Édouard Rossignol des Dunes de Poincy was born in New Orleans to a well-to-do family of French descent, and was part of a group of New Orleans artists whose cultural ties were more closesly related to France than the South or to eastern U.S. cultural centers such as New York City.

His studies in Paris extended from 1852 to 1859, during which time he was influenced by Parisian artists Marc-Charles-Gabriel Gleyre and Léon Cogniet.

[2] On his return to New Orleans, Poincy opened a studio with French-born artist Richard Clague.

The collaboration resulted in the painting Volunteer Firemen's Parade, a noted work completed in 1872.
