The Camorra (Italian: [kaˈmɔrra]; Neapolitan: [kaˈmorrə]) is an Italian Mafia-type criminal organization and criminal society originating in the region of Campania. It is one of the oldest and largest criminal organizations in Italy, dating to the 17th century. The Camorra's organizational structure is divided into individual groups also called "clans". Every capo or "boss" is the head of a clan, in which there may be tens or hundreds of affiliates, depending on the clan's power and structure. Consequently, as Camorra clans act independently, they are more prone to feuding among themselves. The Camorra is considered by the Italian Government to be the most violent, murderous and feared criminal organization in Italy. The FBI considers the Camorra to be among “the most powerful, technologically advanced, well-equipped, sophisticated and dangerous crime syndicates in the world” with a semi-militarized operation. The Camorra's main businesses are drug trafficking, racketeering, counterfeiting, and money laundering. It is also not unusual for Camorra clans to infiltrate the politics of their respective areas.

Since the early 1980s and its involvement in the drug trafficking business, the Camorra has acquired a strong presence in other European countries, particularly Spain. Usually, Camorra clans maintain close contact with South American drug cartels, which facilitates the arrival of drugs in Europe.

According to Naples public prosecutor Giovanni Melillo, during a 2021 speech of the Antimafia Commission, the most powerful groups of the Camorra in the present day are the Mazzarella clan and the Secondigliano Alliance. The latter is an alliance of the Licciardi, Contini and Mallardo clans.
