Sébastien Auguste Baussan (24 May 1829, Avignon – 23 February 1907, Montpellier) was a French sculptor.
Originally from Avignon, Auguste Baussan was trained by his father Joseph Baussan (1791–1871), himself a sculptor, and by the painter Charles Matet in Montpellier.
Baussan actively participated in the Montpellier artistic milieu of the second half of the 19th century with Matet, Michel Maximilien Leenhardt, Édouard-Antoine Marsal and Frédéric Bazille.
He subsequently taught as professor of sculpture at the Montpellier École des Beaux-Arts.
