Temple of Our Lady of Assumption, Catholic church in Arizpe, Mexico.

The Temple of Our Lady of Assumption in Arizpe has a facade divided into three sections by Tuscan pilasters and entablatures. The main entrance, reached by four steps, has a raised-arch doorway; above it are a medallion, a choir window and a curved pediment. A separate bell tower rises in three tapering tiers.

The church was founded in 1646 and ranks among the earliest religious structures built in Sonora during the Spanish colonial period. Its establishment marked an important moment when missionaries and settlers were establishing communities across the region.

The church's dedication changed over time: founded in 1646 as the Misión de Nuestra Señora de la Asunción de Aritpa, it was consecrated as a cathedral in 1779 under the name Nuestra Señora de Loreto, then reduced to a parish a month after Bishop Antonio de los Reyes moved the seat to Álamos. Its main fiesta is held every 15 August for the Assumption.

The main entrance faces southwest from the plaza, which serves as the atrium; two side doors open from the parish house to the northwest and from a garden to the southeast, parallel to Calle Hidalgo. The separate bell tower stands apart from the church body. The building is a listed Historical Monument within the Conjunto Parroquial de Nuestra Señora de la Asunción, which also includes the parish house and the campanario.

The wooden Christ venerated here was brought from Sicily, and the remains of Juan Bautista de Anza, the explorer and governor of Santa Fe de Nuevo México who died in Arizpe in 1788, are buried on the right side of the building. The parish complex also includes the priest's house and a bell tower that stands apart from the church.
