Alfred-Felix Vaucher (March 18, 1887 - May 22, 1993) was a French theologian, church historian and bibliograph. He was a pioneer in the study of Seventh Day Adventisism.

Preaching his first sermon at age 14, Vaucher studied at a church in Paris. In 1903, he was engaged by the adventist church, to which he devoted an active ministry of approximately eighty years.

Vaucher traveled around Europe, including Switzerland and Italy as a Seventh Day Adventist evangelist. He published over 1,100 articles and pamphlets on French church history and wrote two books, L'Histoire du Salut and Le P. Manuel de Lacunza y Diaz. Vaucher also taught at the Collonges, a French biblical college, from 1921 to 1951.
