The Basilica of Saint Augustine (; ) is a Catholic basilica and pro-cathedral located in Annaba, Algeria. It is dedicated to Saint Augustine of Hippo.
Construction of the basilica began in 1881 and finished on March 29, 1900, led by Abbe Pougnet. The church was dedicated April 24, 1914 and dedicated to Saint Augustine of Hippo. It was built not far from the remains of the Basilica Pacis built by Saint Augustine, where he died while the city was besieged by Vandals. The statue of St. Augustine in the basilica contains one of his arm bones. It is under the circumscription of the Diocese of Constantine. In 1842, a portion of Augustine's right arm (cubitus) was secured from Pavia and returned to Annaba. It now rests in the Saint Augustin Basilica within a glass tube inserted into the arm of a life-size marble statue of Augustine.
The basilica was built with stones imported from France. Its Carrara marble, stained glass and massive arches combine Roman, Byzantine and Moorish architecture influences.
