Louis Pierre Vieillot ( French pronunciation: [lwi pjɛʁ vjɛjo]; 10 May 1748 in Yvetot – 24 August 1830 in Sotteville-lès-Rouen) was a French ornithologist.

Vieillot is the author of the first scientific descriptions and Linnaean names of a number of birds, including species he collected himself in the West Indies, as well as North American and South American species discovered but not formally named by Félix de Azara and his translator Sonnini de Manoncourt. He was among the first ornithologists to study changes in plumage and one of the first to study live birds. At least 88 of the genera erected by Vieillot are still in use.
