Ventureño language in the context of Malibu, California

Mission San Buenaventura (Spanish: Misión San Buenaventura, Ventureño: mitsqanaqan̓), formally known as the Mission Basilica of San Buenaventura, is a Catholic parish and basilica in the Archdiocese of Los Angeles. The parish church in the city of Ventura, California, United States, is a Spanish mission founded by the Order of Friars Minor. Founded on March 31, 1782, it was the ninth Spanish mission established in Alta California (or Nueva California) and the last to be established by the head of the Franciscan missions in California, Junípero Serra. Designated a California Historical Landmark, the mission is one of many locally designated landmarks in downtown Ventura.

The mission was named after St. Bonaventure, a 13th-century Franciscan saint, one of the early leaders of the Order to which the friars belonged, and a Doctor of the Church. On June 9, 2020, Pope Francis elevated the church to a minor basilica, and on July 15, 2020, the feast day of its patron saint, the announcement of the Pope's action was made and the elevation of the mission's status was officially proclaimed by Archbishop José Gómez of Los Angeles. The name of the mission was changed to reflect this new status in the Catholic Church.
