Mecca is an unincorporated community located in Riverside County, California, United States. The desert community lies on the north shore of the Salton Sea in the Eastern Coachella Valley and is surrounded by agricultural land.

Situated in the Colorado Desert, Mecca has an arid desert (BWh) climate, experiencing an average temperature of 90 °F. Low temperatures can reach into the 20 °F range. The community sits below 150 feet under sea level on the edge of the Salton Sea.

Land developers intending to irrigate the desert with water from the Colorado River did not foresee excess snow melt, and for two years from 1905 to 1906 accidentally re-routed the entirety of the river to the Salton Sink, flooding the salt mines that had been a source of salt for perhaps centuries and giving rise to the Salton Sea. Groundwater and water transported via the Coachella Canal have transformed the desert environment into large swaths of agricultural land.

The focal point of the community is the Mecca Family and Farm Worker's Service Center. In 1999, California Rural Legal Assistance, Inc., filed 30 complaints of discrimination against Riverside County. The U.S. Department of Housing and Urban Development investigated the complaints and determined that Riverside County's housing policies and code enforcement activities demonstrated a pattern of discrimination against Latino renters and homeowners. The county agreed to construct the Farmworker Service Center as part of a multimillion-dollar settlement agreement entered into to avoid further litigation. The Farmworker Service Center was inaugurated in 2005 and houses a health clinic, day care facility, offices for the Economic Development Department, and provides information and referrals to government services that can be accessed by the community's largely farmworker population.

Following the construction of the Farmworker Service Center, the county committed to other investments including the Mecca-North Shore Community Library and the Mecca Fire Station, both inaugurated in 2011.

Also in 2011, the Boys & Girls Club of Coachella Valley opened its biggest unit in California. Located next door to the Mecca Community Service Center, the club presently [when?] serves c. 350 children from Mecca and surrounding areas.

For many eras, the Desert Cahuilla's native home was the Coachella Valley. The Cahuillas would travel from their village in Martinez to Dos Palmas Spring via an ancient Native American trail known as the Cocomaricopa/Halchidoma Trail. This trail traversed just south of the town of Mecca.

Spanish Explorer Melchior Diaz is the first non-indigenous person to set foot and explore inland California in December 1540 near the Yuma Crossing and Imperial Valley (95 miles southeast from Mecca).

Legend of Juan de Iturbe's Lost Pearl Ship in the Desert is a local legend that after the 1862 Great flood locals reported seeing an ancient Spanish galleon that had beached during a voyage at New Spain's northernmost frontier of water the ancient Lake Cahuilla in 1615. In reported cases, the ship was allegedly seen near Salt Creek (South of Mecca).

Juan Bautista de Anza led a colonizing expedition in 1774, from Mission San Xavier del Bac (Tucson) to San Gabriel Mission (Los Angeles). Anza traveled through the Imperial Valley just south of Mecca and encountered the native Cahuillas becoming the first Spanish to make contact with the Cahuillas.

Spanish missionaries from the San Gabriel Mission in Los Angeles would make the long journey to collect salt from brine pools near the northern Salton sink (South of Mecca) known as the evaporating ancient Lake Cahuilla in 1810.

In 1823 under orders from the Mexican Emperor Agustín de Iturbide to reopen a land route (closed by an Indian Revolt In 1871) from Alta California to Sonora, Captain José Romero and José María Estudillo documented the first recorded expedition into the Coachella Valley. They traversed the Halchidoma Trail and were escorted by the Cahuilla to Dos Palmas Spring(Near Mecca) reaching it on December 31, 1823. They camped for four days before advancing East. Romero's party returned to the Eastern Coachella Valley after getting lost near Palen Lake.

in 1862 William D. Bradshaw connected La Paz Gold mines to Los Angeles using the prehistoric Indian Halchidoma Trail and renaming it the Bradshaw Trail. This trail was used by many travelers traversing from Arizona to California. The railroad would eventually replace the stagecoach trail in the late 1870s. The Stagecoach stop of Lone Palm was located South of Mecca near the town of North Shore.

Southern Pacific constructed a railroad connecting Yuma to Los Angeles. The railroad was completed in 1869. A Railroad Station named Walters was erected and soon the town of Mecca began to populate in the 1870's.

In the late 1890s, the Date Palm was introduced to the Coachella Valley. The plant was farmed in Mecca to a success after the Climate in the town was similar to the plant's native climate in the Middle East.

From 1905 to February 1907, the Colorado River overflowed into the Salton Sink which had an ancient history of previous lake iterations. This time, the engineering disaster led to the creation of the modern Salton Sea. The flood waters never made it to Mecca although it came close to the Town.

On September 7, 1976, a hurricane had a destructive impact on the entire Coachella Valley. This event and further floods in the 1980s stalled progress in the eastern Coachella Valley. In recent history, Mecca has been solidified as an agricultural center for the Eastern Coachella Valley.
