The San Miguel Mission is a historic church in Santa Fe, New Mexico. It is also claimed to be the oldest church in the United States that is still in use and existence.

Also known as the San Miguel Chapel, the San Miguel Mission is a Spanish colonial mission church. It estimated to have been built around 1610 to 1626, and was repaired a couple of times, first from the damage during the 1680 Pueblo Revolt, then in the late 1700s. Despite the several repairs, its original adobe walls are still largely intact.

The San Miguel Mission is a contributing property in the Barrio De Analco Historic District, a US National Historic Landmark. Mass during Sundays are still regularly held at the chapel.
