A passenger has died after jumping from the world’s largest cruise ship on the first night of his week-long voyage, officials said.

The unidentified man jumped from Royal Caribbean’s new 1,200-foot-long Icon of the Seas — which holds 7,600 passengers and 2,350 crew members — soon after it left Florida for Honduras on Sunday morning, the Coast Guard told The Post.

“The cruise ship deployed one of their rescue boats, located the man and brought him back aboard,” the Coast Guard said.

“He was pronounced deceased. Beyond assisting in the search, the US Coast Guard did not have much involvement in this incident,” the agency added.

Royal Caribbean told The Post: “The ship’s crew immediately notified the U.S. Coast Guard and launched a search and rescue operation.

“Our Care Team is actively providing support and assistance to the guest’s loved ones during this difficult time.”

According to CruiseHive, the ship was only about 300 miles from Port Miami at the time of the incident.

The ship stopped for about two hours while members of the crew helped the Coast Guard accomplish its search and rescue mission.

The jumper was brought back onboard in critical condition before he succumbed to his injuries, the report said.

Guests aboard the ship have shared videos about the rescue mission, some expressing shock that the man was initially found alive.

Others shared clips of the rescue boats heading away from the ship to retrieve the passenger.

The Icon of the Seas, the world’s largest cruise ship, took its maiden voyage in January this year.

The ship has 20 decks and is nearly the size of four city blocks.

It boasts a 17,000-square-foot water park with six waterslides and seven pools — including the 40,000-gallon Royal Bay, which is the largest pool at sea — and Absolute Zero, the largest ice skating rink at sea.

There are also a theater, a carousel and more than 40 restaurants, bars and lounges aboard.
