Cocoa is a city in Brevard County, Florida. The population was 19,041 at the 2020 United States Census. It is part of the Palm Bay–Melbourne–Titusville Metropolitan Statistical Area.

Several stories circulate among Cocoa old timers as to how the town got its name. One story says that the mail used to come by river boat and was placed in an empty tin box labeled Baker's Cocoa. The box was nailed to a piling in the river next to downtown. Additionally, an early hotel in the area, located on the Indian River lagoon, was named Cocoa House. Another story speaks of an elderly African American woman who lived on the banks of the Indian River. She would supply hot cocoa to sailors traversing the Indian River. It was said, the sailors approaching her house would yell out "Cocoa! Cocoa!" alerting the woman that they were present and wanted the beverage.

In 1885, the S. F. Travis Hardware store opened. As of 2023, the business remains open. Cocoa's business district was mostly destroyed by fire in 1890. But soon, significant development was stimulated by the extension of the Jacksonville, St. Augustine, and Indian River Railway to Cocoa.

The city was chartered on October 1, 1895. In the winter of 1894–1895, Cocoa had an economic setback when the "Great Freeze" destroyed the citrus crop and forced many citrus workers to seek new jobs. By 1903, the population of Cocoa had declined to 382.

In the 1910s, population growth in Cocoa accelerated. The state business directory of 1911–1912 stated the population was 550.

In October 1918, the mayor of Cocoa proclaimed that all places of assembly, including schools, churches, and movies be closed to avoid spreading the Spanish flu.

By 1925, the population was estimated at 1,800. By 1930, despite the Great Depression, the population had risen to 2,200.

The population rose dramatically following the development of the space industry, quadrupling from 3,098 in 1940 to 12,244 in 1960. Cocoa and the surrounding area also became integrated with the tourist industry for the first time, as thousands visited the area to witness the launches from Cape Canaveral. By 1980, the population had grown to 16,096.

Education was segregated until the 1960s, at which time Monroe High School and elementary schools for black students were closed.

In 1964, the Cocoa Expo Sports Center (Cocoa Stadium) was built for the Colt 45s spring baseball training and Grapefruit League games. The team later became the Houston Astros. In the early 1980s, the city attempted to upgrade the stadium by asking the Astros to pay for needed repairs. In 1985, the team responded by moving its training to Osceola County Stadium in Kissimmee. As a result, it was decided that future negotiations with major league teams would be done by the county government.

Clearlake Middle School was closed in 2013. Students were moved to Cocoa High School, which was converted to a junior and senior high school.

Cocoa first approved the Council-Manager form of government in 1959, and subsequent changes to the state statutes mirrored the City of Cocoa's Council-Manager Plan.

Into the latter 1950s, passengers could take the Dixie Flagler to Chicago via Atlanta from the station. All passenger trains along the FEC were suspended in 1963 due to a strike. The FEC resumed local passenger service between Jacksonville and the Miami area from 1965 until July 31, 1968.

Since 1957, Cocoa has supplied the communities of central Brevard County with potable water. Cocoa made major investments in the water supply and treatment facilities needed to produce a sub-regional water system.

In 2017, Cocoa provided an average of 23,000,000 US gallons (87,000,000 L; 19,000,000 imp gal) of water daily to over 80,000 customers (250,000 people) in Cocoa, Rockledge, Port St. John, Merritt Island, Cape Canaveral, Cocoa Beach, Suntree/Viera, Patrick Air Force Base, Kennedy Space Center and Port Canaveral.

Cocoa's water system includes the wellfield and raw water collection system, Wewahootee Water Treatment Plant, transmission mains, and the Dyal Water Treatment Plant (WTP). Cocoa's drinking water sources include the Floridian Aquifer, Intermediate Aquifer, Taylor Creek Reservoir, and Aquifer Storage and Recovery (ASR) wells. All of these facilities are located in east Orange County. A distribution system and storage pumping facilities are located in Brevard County.

The Dyal WTP processes about nine billion gallons per year, with peak flows reaching 38 million gallons per day (mgd) during the summer. Daily flows average 25 mgd. The Dyal WTP is unusual for Central Florida because it is capable of treating both ground and surface water.

The flag was originally painted on the water tower free of charge by a Greek immigrant. He wanted to decorate the tower in time for the United States Bicentennial celebration in 1976. In 2014, the City re-furbished and re-painted the tower with the iconic American flags.
