Menifee is a city in Riverside County, California, United States, and part of the Los Angeles Combined Statistical Area. The city is centrally located in the heart of Southern California, almost 15 miles (24 km) north of Temecula and bordering the city of Murrieta. Menifee is roughly 46 square miles (100 km2) in size and has an elevation of 1,424 feet (434 m). The incorporated City of Menifee includes the communities of Sun City, Quail Valley, Paloma Valley, and Romoland.
The area was originally inhabited by the Luiseño people, specifically the Pechanga band. In the 18th century, the area fell under Spanish rule and was ceded by Mexico to the United States in 1850 as a result of the Mexican–American War.
Farming, which began in the mid-19th century, was concentrated in the Menifee area. Mining began in the early 1880s with the discovery of a significant quartz lode by miner Luther Menifee Wilson, from whom Menifee derived its name.
Early development of the Menifee area began with Sun City in the early 1960s, conceptualized as an active retirement community by Del Webb, a building contractor from Phoenix, Arizona. Webb also developed Sun City, Arizona, under the same concept.
