Hagan is a ghost town in Sandoval County, New Mexico, United States, about 13 miles (21 km) southeast of San Felipe Pueblo.

Work on the spur was begun in 1908 but was suspended within months, stalling development of the community of about 60 residents for a decade.

Over 100 adobe structures were built by adobero Abenicio Salazar of Bernalillo with a team of 100 laborers and 60 masons over a period of three years, in the Pueblo Revival style which was popular at the time.

The town grew from 1924 to 1930 and the population peaked at about 200 people, mostly Italian and Slavic miners from the coalfields of Raton and Dawson, and local Hispanos from Madrid and Los Cerrillos.

Only the foundations and a few brick walls of the power plant, general store, reservoir, and a few smaller buildings remain.
