Moroccan police said it seized on Tuesday 1.488 tonnes (3,280 lb) of cocaine concealed in banana boxes in the northern Tanger Med port.
The drug was found in a container on a Turkey-bound ship with a European flag departing from South America, the police said in a statement.
The operation was conducted in coordination with Spanish security services, the Moroccan police said, noting that investigations are ongoing.
The bust comes just a day after authorities seized nearly 363kg of cocaine from a truck attempting to enter Morocco through the border with Mauritania.
The northern African country has been identified as a key route for smuggling drugs from South America to Europe.
