Muscoy is a census-designated place (CDP) in San Bernardino County, California, United States. The population was 10,644 at the 2010 census, up from 8,919 at the 2000 census. Muscoy shares zip code 92407 with northwest San Bernardino, California's Verdemont neighborhood, Devore Heights, and Arrowhead Farms. Residents enjoy a semi-rural setting with large lots where they can raise horses and other livestock, nursery plants, and fruit trees. For this purpose, much of Muscoy is included in the county Additional Agriculture (AA) overlay. This overlay specifies types and quantities of animals that may be kept on each parcel. A distinctive feature of Muscoy life today is motor vehicles and equestrians sharing the roadways.
Muscoy was developed in the mid-1920s as a community designed to accommodate family agricultural enterprises. Roads and water service were developed to serve one to ten acre parcels. Vineyards, orchards and various field crops were planted and cultivated. After World War II, population growth accelerated and the area began a transition from agricultural use to a more suburban residential character. During the 1950s and 1960s, Route 66, which connected California with Nevada and Arizona, made the San Bernardino area a popular stop during road trips. This resulted in more shops opening up to serve the needs of travelers, and more people establishing permanent residences around the Muscoy area.
According to the United States Census Bureau, the CDP has a total area of 3.1 square miles (8.0 km2), 99.87% of it is land and 0.13% is water.
Muscoy is bordered on the west by Lytle Creek wash, most of the time a dry river bed, other times the scene of raging flash floods. At one time the wash was the home of many species of flora and fauna, including the San Bernardino kangaroo rat and the Muscoy Muskrat which have now mostly disappeared.
