Montes Alpes is a mountain range in the northern part of the Moon's near side. It was named after the Alps in Europe; the name was confirmed by the International Astronomical Union in 1935. It lies between the selenographic coordinates latitudes 52.81°N and 42.04°N, and longitudes 5.6°W and 3.22°E. The range thus crosses the lunar prime meridian, and is partially illuminated and partially in shadow during first and last quarters. The center of the range is at 48.36°N, 0.58°W, and has a diameter of 334 km.
