Louis-Xavier Eyma (16 October 1816 – 20 March 1876) was a 19th-century French journalist and writer, author, among others, of novels, travel books and theater plays.

An editor at the Journal des actionnaires when he was back in France, he returned in 1858 to New-Orleans where his father lived, and worked there as director of the French section of L'Abeille (1858–1859).

Among several American personalities, he engaged into a friendship with Washington Irving and visited the plains of Ohio, Mammoth Cave, Leavenworth and Philadelphia.

Although an admirer of the United States, Eyma condemned slavery and the massacre of Indians in his writings.

He then visited Cuba and after he returned to France in 1861, he worked for many newspapers including Le Figaro and La Liberté.
