Gardaí have held a press conference in Dublin putting €37.5m worth of seized herbal cannabis on display.
The seizure was made as part of ongoing joint investigations, targeting organised crime groups.
The consignment arrived into Dublin Port, and a subsequent search resulted in the seizure of 1,873kg of herbal cannabis.
Joint investigations are continuing both domestically and internationally with regard to the seizure.
Authorities say the drugs were destined for the Irish market.
Tánaiste and Justice Minister, Frances Fitzgerald, has commended the work of An Garda Síochána and Revenue's Customs Service.
She said: '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.
"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.
"The Government will continue to fully support both An Garda Síochána and the Customs Service in carrying out this vital work."
