The Barrio de Analco Historic District is a National Historic Landmark District centered at the junction of East De Vargas Street and Old Santa Fe Trail in Santa Fe, New Mexico.

The seven buildings of the district represent one of the oldest clusters of what were basically working-class or lower-class residences in North America, and are in a cross-section of pre-statehood architectural styles.

[2][3] The Barrio de Analco is located on the south side of the Santa Fe River, across the river from the main downtown area that includes the Santa Fe Plaza and the Palace of the Governors.

The barrio was established not long after Santa Fe's founding in 1609-10, as a district for artists, laborers, and servants, while the area north of the river was occupied by the wealthy and powerful.

The buildings in this district, largely built to serve that type of community through several centuries, document the changes in architecture from a nearly pure native adobe construction (the "Oldest House"), to the Spanish Pueblo style, and then the Territorial.
