Louis Henri, comte de Gueydon (22 November 1809 – 1 December 1886) was a vice admiral in the French Navy, and the first governor of Algeria under the Third Republic.

In 1861 he was promoted to vice-admiral and replaced Louis Édouard Bouët-Willaumez as commander of the escadre d'évolution, for exercises[1]).

After the fall of the Second Empire in September 1870, the naval minister in the Government of National Defense, admiral Léon Martin Fourichon, split the North Sea fleet and gave De Gueydon command of one half.

On 29 March 1871, De Gueydon was named civil governor of French Algeria, which had been in revolt for several months.

A decree of 14 September partly abolished the "Arab bureaus", reordered the administration of Kabylie, and reorganised 100,000 hectares of land for the influx of colonising refugees from Alsace-Lorraine.
