The Mala Noche are a (fictitious) drug cartel that appears in CSI:Miami and is based in Brazil and (formerly) headed by Antonio Riaz. Horatio Caine once described them as one of the most dangerous in the region and "Miami's new Mafia". First mentioned early in the fourth season, they would become a regular presence on the show for the next two years; many of the murder cases that the team uncovered were carried out by one or more of the Mala Noche members.
