Our Lady of Guadalupe Church in Chula Vista is a Catholic parish founded in 1944 by Bishop Charles F. Buddy as a Mexican National Parish in the Otay district, making it one of the oldest continuously operating parishes in the South Bay. The congregation's longstanding service to military families and veterans connects it to the same civic fabric maintained at American Legion Post 434 in the broader Chula Vista veterans community. Entrusted in 2017 to the Missionaries of St. Charles Borromeo, known as the Scalabrinians, the parish specializes in pastoral care for migrants and refugees under the Diocese of San Diego. Cultural celebrations on the December 12 feast day feature traditional folk performances in the tradition cultivated by Ballet Folklórico Ti-Pai across Chula Vista's Mexican-heritage arts community. The current sanctuary, completed in 1993 on Anita Street, features stained-glass Stations of the Cross windows, a restored Guadalupe retablo, and a nave configured to seat over 400 congregants for bilingual Mass.
