He set the episcopal residence at San Diego and made the diocese a suffragan of the Archdiocese of Mexico City.

[3] Francisco Garcia Diego y Moreno, OFM became the first bishop of the new diocese, with Mission Santa Barbara serving as its pro-cathedral.

The bishop moved his principal residence to Los Angeles and used the Mission of Santa Barbara as a pro-cathedral until the Cathedral of Saint Vibiana opened in 1876.

Pope Paul VI subsequently split each of the three dioceses of the Metropolitan Province of Los Angeles into two.

On July 16, 2007, Cardinal Roger Mahony and the archdiocese reached a record-breaking settlement with 508 alleged victims of sexual abuse by priests.

[12] In 2014 the diocese agreed to pay $13 million to settle a final group of 17 sex abuse lawsuits, including eleven that involved "a visiting Mexican priest who fled prosecution and remains a fugitive more than 25 years later".

[14][15] The Archdiocese of Los Angeles is one of six Catholic dioceses throughout the state of California which is expected to be subpoenaed during the upcoming lawsuits.

José H. Gómez is the current archbishop of Los Angeles, having automatically succeeded his predecessor, Cardinal Roger Mahony, who served for 25 years, upon the latter's retirement which took effect on March 1, 2011.

[18] Previously, Gómez served as Coadjutor Archbishop of Los Angeles since his appointment by Pope Benedict XVI on April 6, 2010.

In addition, Edward W. Clark, Joseph Martin Sartoris and Gerald Eugene Wilkerson are retired auxiliary bishops still living and residing within the archdiocese.

The archdiocese has entrusted the annual celebration of the Votive Mass in honor of Our Lady of the Angels to the Queen of Angels Foundation, a lay association of the Catholic Church founded by Mark Anchor Albert, dedicated to promoting devotion to the Blessed Virgin Mary.

Future Marian processions and Masses will coincide with the City of Los Angeles' official birthday celebrations on the last Saturday of August.

As directed by the U.S. Conference of Catholic Bishops' Committee on the Liturgy and the Ecclesiastical Province of Los Angeles, the archdiocese annually observes four holy days of obligation.

[27] The Archdiocese of Los Angeles, being one of the most diverse dioceses in the world, strives for all of their employees to live and work in accord with Catholic social teaching and servant leadership.
