Herbal cannabis with an estimated value of €37.5 million has been seized at Dublin Port.
The seizure was made as part of an investigation by gardaí and officers from Revenue's Customs Service.
It is the largest drug seizure in the country in years and is the result of an ongoing investigation into a Dublin-based criminal gang.
The drugs were discovered concealed in 'wide load' containers which were labelled as containing machinery parts.
The 1,873kgs of cannabis arrived at the port on a ship from Europe. The drugs were vacuum packed and concealed to avoid detention by X-rays and sniffer dogs.
No arrests have been made.
Authorities believe the drugs were destined for the Irish market.
Tánaiste and Minister for Justice Frances Fitzgerald commended the gardaí and Revenue's Customs Service for the seizure.
"Week in week out the gardaí and Customs work very closely in trying to prevent the importation of illicit drugs into the country and they have many successes," she said.
"Today's seizure, in particular, demonstrates their determination and resourcefulness in going after the activities of drugs gangs who seek to profit from causing such misery in communities through their deadly trade," said Ms Fitzgerald.
