Corona is a Mexican brand of beer produced by Grupo Modelo in Mexico. It is brewed, exported, and distributed globally by Grupo Modelo's parent company AB InBev. In the United States and Guam, Constellation Brands is the exclusive licensee and sole importer distributor of Corona. The beer is also brewed in China for the Australasia market. It is the top-selling brand of imported beer in the United States.It is often served with a wedge of lime or lemon in the neck of the bottle to add tartness and flavor. The recipe for the mash bill includes corn as well as the barley malt and hops traditionally used for making beer.

The brand's most popular variation is Corona Extra, a pale lager. It is one of the top-selling beers worldwide, and Corona Extra has been the top-selling imported drink in the U.S. since 1998. Other variants of the Corona beer brand include Corona Light, Corona Premier, and Corona Familiar. A variety of flavored hard seltzers marketed under the Corona brand name was launched in March 2020.

In July 1922 German immigrant and brewmaster, Adolph H. Schmedtje joined Cerveceria Modelo Sociedad Anónima (S.A.) to oversee production and created the Corona brew. Corona was officially introduced in 1925. In 1932 Cerveceria Modelo S.A. changed ownership and after a period of acquisition consolidated into Grupo Modelo. With the reduction of tariffs on the import of Mexican beer to the United States when NAFTA came into effect in 1994, along with an increase in immigration between the two countries, Corona grew in popularity in the United States.

In 2013, Anheuser-Busch InBev acquired full control of Grupo Modelo. To satisfy the United States Department of Justice's antitrust concerns, Anheuser-Busch InBev transferred all United States distribution rights to Corona and Grupo Modelo's other brands to Constellation Brands.

According to Sinebrychoff, a Finnish company owned by the Carlsberg Group, Corona Extra contains barley malt, corn, hops, yeast, antioxidants (ascorbic acid), and propylene glycol alginate as a stabilizer.

The label and logo of Corona was designed by Eduardo Cataño working under the advertising company Galas de México for Grupo Modelo brewery, around 1935.

Corona beer is available in a variety of bottle presentations, ranging from the 207 ml (7.0 U.S. fl oz; 7.3 imp fl oz) ampolleta (labeled Coronita and just referred as the cuartito) up to the 940 ml (31.8 U.S. fl oz; 33.1 imp fl oz) Corona Familiar (known as the familiar, Litro or Mega). A draught version also exists, as does canned Corona in some markets.^{[citation needed]}

Since the 80s, Corona had been branded as Coronita (literally, 'little crown') in Spain, as winemaker Bodegas Torres had owned the trademark for "Coronas" since 1907. The packaging was otherwise the same in Spain as in Mexico and the United States. AB InBev resolved the branding issues with Torres in 2016, with the beer starting to be sold as Corona in Spain from June of that year. In Mexico, the United Kingdom, Canada, Australia, and the United States, smaller, 210 mL (7.4 imp fl oz) bottles of the beer are also branded as "Coronita".
