The Roman Catholic Archdiocese of Lima is part of the Catholic Church in Peru which enjoys full communion with the Holy See. The Archdiocese was founded as the Diocese of Lima on 14 May 1541. The diocese was raised to the level of a metropolitan archdiocese by Pope Paul III on 12 February 1546. One of its archbishops was the saint Torribio Mogrovejo.

Lima, founded in 1535 as the Ciudad de los Reyes, is the capital and largest city of Peru. It is located in the valleys of the Chillón, Rímac and Lurín Rivers, in the desert zone of the central coastal part of the country, overlooking the Pacific Ocean. The city is considered the political, cultural, financial and commercial center of Peru. Due to its geostrategic importance, the Globalization and World Cities Research Network has categorized it as a "beta" tier city. Jurisdictionally, the metropolis extends mainly within the province of Lima and in a smaller portion, to the west, within the Constitutional Province of Callao, where the seaport and the Jorge Chávez Airport are located. Both provinces have regional autonomy since 2002.
