Dania Beach (Dania until 1998) is a city in Broward County, Florida, United States. It is part of the Miami metropolitan area. As of the 2020 census, the city's population was 31,723. Dania Beach is the location of one of the largest jai alai frontons in the United States, The Casino @ Dania Beach (Dania Jai Alai). It was formerly the location for two amusement centers; one named Boomers! (formerly Grand Prix Race-O-Rama), which housed the Dania Beach Hurricane roller coaster, and the other being Pirates World amusement park, which was featured in Barry Mahon's Thumbelina. It is also home to the International Game Fish Association Hall of Fame and Museum.

The area was started as a neighborhood called Modello in the late 19th century. In November 1904, the area was incorporated as the "Town of Dania", because most of the 35 residents were farmers of Danish ancestry. On January 4, 1926, Dania voted to annex itself to the City of Hollywood.

After the September 1926 Miami hurricane decimated Hollywood's fortunes, most of Dania seceded from the City of Hollywood and reincorporated as a city. The areas that chose to remain part of the City of Hollywood caused Dania's current noncontinuous city boundaries. In November 1998, the "City of Dania" formally changed its name to "City of Dania Beach". The name "Dania" is still commonly used to refer to the city.

In 2001, the city annexed several unincorporated areas of Broward County, increasing its population by about 3,600 people.

Formerly known as the "Tomato Capital of the World", once the city went from a farming settlement to an urban city, it soon took on the name "Antique Capital of the South", due to many antique shops in downtown Dania Beach, especially along Federal Highway, known as the city's "Antique Row".
