The Eller Apartments are a historic apartment building in Albuquerque, New Mexico. The apartments were built in 1922 by Dr. Charles A. Eller (1879–1967), a prominent local dentist, and are believed to be the city's second oldest apartments after the Washington Apartments. The building was designed by Trost & Trost of El Paso and built by E. J. Marchant, the same team who completed the no longer extant Castle Apartments the same year. The apartments were positioned at the luxury end of the market and were home to well-known residents including former Governor Merritt C. Mechem. The building was added to the New Mexico State Register of Cultural Properties in 1983 and the National Register of Historic Places in 1984.
