Count Louis Philippe de Roffignac[1] (also known as Joseph Roffignac) (September 13, 1773[2] – August 29, 1846) was a wealthy Louisiana merchant, banker, member of the state legislature, and the tenth individual to serve as Mayor of New Orleans, in 1820-1828.

At the age of fourteen he was a page in the household of his godmother, Louise Marie Adélaïde de Bourbon, Duchess of Orléans;[3] at seventeen, he joined the French army as a lieutenant of artillery.

He used the money to improve and beautify the city: he was responsible for the massive planting of trees as well the first street paving.

He died at his château, near Périgueux, under curious circumstances: according to the medical examiner called in to determine the precise cause of his death, he had been sitting in his invalid chair, examining a loaded pistol, when he was suddenly overwhelmed by an apoplectic stroke and fell to the floor; in the fall, the pistol fired into his brain.

His name is also commemorated in the Roffignac cocktail, invented about 40 years after his term as mayor, popular locally until the 1960s.
