California is a state in the Western United States, located along the Pacific Coast. With nearly 39.2million residents across a total area of approximately , it is the most populous U.S. state and the third-largest by area. It is also the most populated subnational entity in North America and the 34th most populous in the world. The Greater Los Angeles and San Francisco Bay areas are the nation's second and fifth most populous urban regions respectively, with the former having more than 18.7million residents and the latter having over 9.6million. Sacramento is the state's capital, while Los Angeles is the most populous city in the state and the second most populous city in the country. San Francisco is the second most densely populated major city in the country. Los Angeles County is the country's most populous, while San Bernardino County is the largest county by area in the country. California borders Oregon to the north, Nevada and Arizona to the east, the Mexican state of Baja California to the south; and it has a coastline along the Pacific Ocean to the west.

The economy of the state of California is the largest in the United States, with a $3.37 trillion gross state product (GSP) . It is the largest sub-national economy in the world. If California were a sovereign nation, it would rank as the world's fifth-largest economy , behind Germany and ahead of India, as well as the 37th most populous. The Greater Los Angeles area and the San Francisco area are the nation's second- and fourth-largest urban economies ($1.0trillion and $0.6trillion respectively ), following the New York metropolitan area's $1.8trillion. The San Francisco Bay Area Combined Statistical Area had the nation's highest gross domestic product per capita ($106,757) among large primary statistical areas in 2018, and is home to five of the world's ten largest companies by market capitalization and four of the world's ten richest people. Slightly over 84 percent of the state's residents hold a high school degree, the lowest high school education rate of all 50 states.

Prior to European colonization, California was one of the most culturally and linguistically diverse areas in pre-Columbian North America and contained the highest Native American population density north of what is now Mexico. European exploration in the 16th and 17th centuries led to the colonization of California by the Spanish Empire. In 1804, it was included in Alta California province within the Viceroyalty of New Spain. The area became a part of Mexico in 1821, following its successful war for independence, but was ceded to the United States in 1848 after the Mexican–American War. The California Gold Rush started in 1848 and led to dramatic social and demographic changes, including large-scale immigration into California, a worldwide economic boom, and the California genocide of indigenous peoples. The western portion of Alta California was then organized and admitted as the 31st state on September 9, 1850, following the Compromise of 1850.

Notable contributions to popular culture, for example in entertainment, sports, music, and fashion, have their origins in California. The state also has made noteworthy contributions in the fields of communication, information, innovation, education, environmentalism, entertainment, economics, politics, technology, and religion. It is the home of Hollywood, the oldest and one of the largest film industries in the world, which has had a profound influence upon global entertainment. It is considered the origin of the American film industry, hippie counterculture, beach and car culture, the personal computer, the internet, fast food, diners, burger joints, skateboarding, and the fortune cookie among other innovations. Many full-service restaurants, such as IHOP, Denny’s, and Cheesecake Factory, were also invented in the state. The state is also notable for being home to many amusement parks, such as Disneyland, Six Flags Magic Mountain, Knotts Berry Farm, Universal Studios Hollywood, and many others. The San Francisco Bay Area and the Greater Los Angeles Area are widely seen as the centers of the global technology and film industries, respectively. California's economy is very diverse: 58% of it is based on finance, government, real estate, technology, professional, scientific, technical and business services, architecture, academia, accountancy, marketing, law, market research, business and executive management, economics, consulting, customer support, human resources, information technology, engineering, research and development, design, public relations, education, healthcare, transportation, trade, hospitality, leisure, utilities, tourism, manufacturing, construction, roofing, shipping, warehousing, food processing, trucking, mining, oil field work, recycling, maintenance, custodial work, logging, landscaping, waste collection and disposal, and many other industries. Although agriculture (including hunting, farming, and fishing) accounts for only 1.5% of the state's economy, California's agriculture industry has the highest output of any U.S. state. California's ports and harbors handle about a third of all U.S. imports, most originating in Pacific Rim international trade.

The state's extremely diverse geography ranges from the Pacific Coast and metropolitan areas in the west to the Sierra Nevada mountains in the east, and from the redwood and Douglas fir forests in the northwest to the Mojave Desert in the southeast. Two-thirds of the nation's earthquake risk lies in California. The Central Valley, a fertile agricultural area, dominates the state's center. California is well known for its warm Mediterranean climate along the coast and monsoon seasonal weather inland. The large size of the state results in climates that vary from moist temperate rainforest in the north to arid desert in the interior, as well as snowy alpine in the mountains. Drought and wildfires are a persistent issue for the state. California has established a state program in recognition of Native American use of fire in ecosystems to mitigate wildfires.
