Waldo is a ghost town in Santa Fe County, New Mexico, United States.

[1] The community was created along the Atchison, Topeka and Santa Fe Railway just west of Cerrillos.

Today little remains, although the name appears on a freeway exit on Interstate 25, some distance to the west.

Waldo was at the junction of the AT&SF main east–west line and the Madrid spur.

The ovens were on the south side of the rail line, and the town on the north.
