Its population was 218 at the 2010 census. It is located approximately 18 miles south of the city of Santa Fe. The community was named for Archbishop Jean-Baptiste Lamy, and lies within the Bishop John Lamy Spanish Land Grant, which dates back to the eighteenth century. It had previously been known as Galisteo Junction since it contained the closest railway stop at the time to Galisteo, New Mexico but the similarity in names of the two towns led to confusion in the delivery of postal mail. Jean-Baptiste Lamy's influence over this area includes his creation of Santa Fe's first English teaching school, as well as establishing other similar institutions.
