Coronado (Spanish for "Crowned") is a resort city in San Diego County, California, United States, across San Diego Bay from downtown San Diego. It was founded in the 1880s and incorporated in 1890. Its population was 20,192 in 2020, down from 24,697 in 2010.

Coronado is a tied island which is connected to the mainland by a tombolo (a sandy isthmus) called Silver Strand. Along the coast of Southern California lies four islands that were spotted by Sebastian Vizcaino and his crew. They named them “Los Coronados.” In the mid-1880s, businessmen bought the peninsula near Los Coronados with hopes to turn it into a resort. Later in 1886, the owners of this peninsula hosted a naming contest with the people resulting in the name “Miramar” winning, which was soon overturned due to the public not being satisfied with the name, so they borrowed from their cousin islands “Los Coronados” and named it “Coronado.” The explorer Sebastian Vizcaino drew its first map in 1602. Coronado is Spanish term for "crowned" and thus it is nicknamed The Crown City. Its name is derived from the Coronado Islands, an offshore Mexican archipelago. Three ships of the United States Navy have been named after the city, including USS Coronado.

Prior to European settlement, Coronado was inhabited by the Kumeyaay, who sustained fishing villages on the peninsula in North Island and on the Coronado Cays. As American settlers moved into the area, the Kumeyaay were pushed out of Coronado, with the last six Kumeyaay families deported to Mesa Grande Reservation in 1902.

Coronado was incorporated as a town on December 11, 1890. The community's first post office predates Coronado's incorporation, established on February 8, 1887, with Norbert Moser assigned as the first postmaster. The land was purchased by Elisha Spurr Babcock, Hampton L. Story, and Jacob Gruendike. Their intention was to create a resort community, and in 1886, the Coronado Beach Company was organized. By 1888, they had built Hotel del Coronado, and the city became a major resort destination. They also built a schoolhouse and formed athletic, boating, and baseball clubs.

In 1900, a tourist/vacation area just south of Hotel del Coronado was established by John D. Spreckels and named Tent City. Spreckels also became the hotel's owner. Over the years, the tents gave way to cottages, the last of which was torn down in late 1940 or early 1941.

In the 1910s, Coronado had streetcars running on Orange Avenue. These streetcars became a fixture of the city until their retirement in 1939.

On New Year's Day 1937, during the Great Depression, the gambling ship SS Monte Carlo, known for "drinks, dice, and dolls", was shipwrecked on the beach about a quarter mile (400 m) south of Hotel del Coronado.

In 1946, an African-American man from Coronado named Alton Collier was forced off of a San Diego and Coronado ferry by white sailors. The case was ruled a suicide until 2024, when the Equal Justice Initiative declared a lynching.

In 1969, the San Diego–Coronado Bridge was opened, allowing much faster transit between the cities than bay ferries or driving via State Route 75 along the Silver Strand. The bridge is made up of five lanes, one of which is controlled by a moveable barrier that allows for better traffic flow during rush hours. In the morning, the lane is moved to create three lanes going southbound towards Coronado, and in the evening it is moved again to create three lanes going northbound towards downtown San Diego.

What is Now known as the Naval Air Station on North Island Coronado, was once the first-ever Flying school in America. Glenn Curtiss is known for his incredible engines, which have broken and established many records in distance and speed. He first started with motorcycle engines, having owned many bicycle and motorcycle shops. His incredible success with motorcycle engines led him to aviation. Coronado’s nice weather and protected bay caught his eye, and he managed to get a three-year lease. This is the same piece of land that now stands as one of the most notable Naval Air bases in the United States. “In 1911 he established his flying school at North Island on San Diego Bay, training the pioneer Army and Navy pilots. Among his historic achievements in San Diego was the development of the first practical amphibious aircraft.” During this time he created a new type of seaplane. “In the early 1900s, aviation pioneer Glenn H. Curtiss was a key contributor to the development of the U.S. Navy’s initial aviation program, including the first aircraft to launch from a ship. He invested much of his time and effort in seaplanes (aircraft fitted with floats instead of wheels or skids for landing gear), and his first seaplane designs were light, fast and maneuverable and destined to become the most widely-built aircraft in the U.S. prior to the World War I.” Glenn Curtiss created the first-ever military flying school in America teaching Navy and Army personnel to Fly. The first-ever Amphibious Seaplane flight is one of the many events that established the U.S. Naval Base that now stands in its place. Naval Aviation was born on this base.

According to the United States Census Bureau, the city has a total area of 32.7 square miles (85 km); 7.9 square miles (20.5 km) of the city is land and 24.7 square miles (64 km) of it (75.72%) is water.

Geographically, Coronado is a tied island connected to the mainland by a tombolo known as the Silver Strand. The Silver Strand, Coronado and North Island, form San Diego Bay. Since recorded history, Coronado was mostly separated from North Island by a shallow inlet of water called the Spanish Bight. The development of North Island by the United States Navy prior to and during World War II led to the filling of the bight by July 1944, combining the land areas into a single body. The Navy still operates Naval Air Station North Island (NASNI or "North Island") on Coronado. On the southern side of the town is Naval Amphibious Base Coronado, a training center for Navy SEALs and Special warfare combatant-craft crewmen (SWCC). Both facilities are part of the larger Naval Base Coronado complex. Coronado has increased in size due to dredge material being dumped on its shoreline and through the natural accumulation of sand. The "Country Club" area on the northwest side of Coronado, the "Glorietta" area and golf course on the southeast side of Coronado, most of the Naval Amphibious Base Coronado, most of the Strand Naval Housing, and most of the Coronado Cays (all on the south side of Coronado) were built on dirt dredged from San Diego Bay.

According to the Köppen climate classification system, Coronado has a semi-arid climate, abbreviated "BSk" on climate maps.

Coronado has long been a Republican stronghold; in 2013, about 47% of voters were registered Republican, 25% Democratic, and 24% nonpartisan.

Prior to 2020, the resort city had voted for the Republican nominee in each presidential election since at least 1964.

However the city has been trending Democratic in recent years, with each of the last four Republican presidential candidates receiving less than 60% of the vote. In 2016, Donald Trump won Coronado with a plurality of the vote, and Hillary Clinton received the largest share of the vote for a Democratic candidate since at least 1960.

After California state law mandated that localities zone for affordable housing across the state, Coronado refused to comply with the law. Coronado mayor Richard Bailey described the housing development as "central planning at its worst" and refused to submit a housing plan that allows for construction of the required amount of homes.

Tourism is an essential component of Coronado's economy. This city is home to three major resorts (Hotel del Coronado, Coronado Island Marriott, and Loews Coronado Bay Resort), as well as several other hotels and inns. The downtown district along Orange Avenue, with its many shops, restaurants and theaters, is also a key part of the local economy. Many of the restaurants are highly rated and provide a wide variety of cuisine choices.

Golf on Coronado started in 1897 with a nine hole golf course hosting the 1905 Southern California Open. Later, golf on Coronado migrated to a new site in the Southern portion of the island with 18 holes designed by Jack Daray Sr.. Golf is a popular diversion on the island, entertaining 90,000 golf rounds annually.

In 2008, the Travel Channel rated Coronado Beach as the sixth-best beach in America.

Hotel del Coronado, built in 1888, has been designated as a National Historic Landmark. Its guests have included American presidents George H. W. Bush, Jimmy Carter, Bill Clinton, Gerald Ford, Lyndon B. Johnson, Richard Nixon, Ronald Reagan, Franklin D. Roosevelt, and William Howard Taft, as well as Muhammad Ali, Jack Dempsey, Thomas Edison, Magic Johnson, Charles Lindbergh, Willie Mays, Babe Ruth, Oprah Winfrey, and Robert Downey. Actresses Mary Pickford and Marilyn Monroe also stayed here.

"The Del" has appeared in numerous works of popular culture and was said to have inspired the Emerald City in The Wonderful Wizard of Oz. It is rumored that the city's main street, Orange Avenue, was Baum's inspiration for the yellow brick road. Other sources say Oz was inspired by the "White City" of the Chicago World's Fair of 1893. Author L. Frank Baum would have been able to see the hotel from his front porch overlooking Star Park. Baum designed the crown chandeliers in the hotel's dining room.

Once owned locally, Hotel Del Coronado is now owned by Blackstone (60%), Strategic Hotels & Resorts Inc. (34.5%), and KSL Resorts (5.5%). When Strategic Hotels & Resorts Inc. bought its stake in 2006, the hotel was valued at $745 million; as of 2011, the hotel was valued at roughly $590 million.

Scenes from Denzel Washington's film Antwone Fisher were shot in Coronado. Parts of Brian De Palma's film Scarface and Ron Howard's film Splash were shot at Coronado Beach. A film called Carbon featuring Randy Davison was shot in Coronado near the restaurant Nado Republic.

Principal photography for most films took place at Hotel del Coronado.

Coronado Unified School District includes Coronado Middle School (CMS), Coronado High School, Silver Strand Elementary, and Village Elementary. Coronado School of the Arts, a public school-within-a-school, is located on the campus of Coronado High School.
