French Roman Catholic missionary who was instrumental in securing a French protectorate over Cambodia in 1863.

On arriving in Cochinchina (now part of southern Vietnam) in 1836, Father Miche was promptly condemned to death by the Vietnamese emperor, Minh Mang, who objected to Christian missionary activity in his realm. Miche was soon captured and remained imprisoned until his rescue on March 19, 1843.

In 1856, at the instigation of French diplomat Louis-Charles de Montigny, Father Miche tried unsuccessfully to get the Cambodian king, Duong, to accept French help in ridding Cambodia of Siamese domination. By 1863–64 he had gained the confidence of Duong's successor, King Norodom, and he and a naval officer, Ernest Doudart de Lagrée, induced the King to allow the French to establish a protectorate over his domain.

Miche was named chief apostolic vicar of Cambodia in 1864 and spent the remaining years of his life in missionary activities. He compiled a Latin-Cambodian dictionary and also wrote a number of letters in Annales de la propagation de la foi (1863; “Annals of the Propagation of the Faith”), which give an account of events of the times.
