Immaculate Conception Cathedral, Iquique, Roman Catholic cathedral in Iquique, Chile.

The Immaculate Conception Cathedral is a neoclassical building in Iquique with delicate ornamental details adorning its facade and serving as a major religious structure in northern Chile. The building occupies a prominent location in the city and shapes the urban landscape with its distinctive architectural style.

The parish church of Iquique burned on 10 May 1833, and the Apostolic Vicar Camilo Ortúzar launched a fundraising campaign to replace it. The new church was consecrated in 1882 under the patronage of the Immaculate Conception, and construction was completed in 1885. In May 1884 the remains of Arturo Prat and other fallen of the naval Battle of Iquique were moved into the temple, where they stayed until 1888. In 1929 the creation of the Diocese of Iquique raised the church to cathedral rank.

The cathedral is dedicated to the Immaculate Conception of Mary, its patron since consecration in 1882. Interior decoration includes work by the painter Sixto Rojas Acosta. In 1989 the church and the parish houses attached to it were declared a National Historic Monument, a status visible in the protected complex.

The building stands at the intersection of Calle Obispo Labbé and Esmeralda and is open to visitors who wish to explore its architectural features. The central location makes it easy to visit as part of a walking tour through Iquique.

In 1884 the cathedral temporarily housed the remains of naval officer Arturo Prat and other soldiers killed in the Battle of Iquique. This episode connects the religious significance of the place with an important military historical event in Chilean history.
