The victim, aged in his 40s, had been taking part in a diving trip at Inishtrahull Island around four miles off Malin Head when he surfaced unconscious early on Sunday morning.
He was airlifted to Altnagelvin Hospital but was later pronounced dead.
A rescue helicopter from Prestwick in Scotland was involved in the operation after being diverted from another incident at Fair Head, near Ballycastle along the North Coast.
A man had been discovered on the rocks with a suspected broken ankle.
The helicopter, as well as an RNLI lifeboat and a coastguard team from Ballycastle, went to his assistance at around 6.20am.
When they arrived a paramedic was winched to the scene - however the crew had to pull out of the rescue in order to attend the diving emergency off the Co Donegal coast.
The RNLI said: "Due to another emergency off the Donegal coast the helicopter had to immediately recover their winch-man and make best speed to assist in the other emergency.
"In a difficult operation the lifeboat crew and coastguards placed the injured man into a stretcher and recovered him from the rocks to the lifeboat."
The patient was transferred to an ambulance at Ballycastle Harbour in a stable condition.
