A great white shark might soon be surfacing in the Big Apple.

Mary Lee, a massive maneater with her own Twitter page, may also be pregnant, a scientist told The Post Saturday.

The 16-foot-long, 3,500-pound beast who became a social-media star after biologists tagged her in 2012 and began tracking her — was “pinged” Saturday near Island Beach State Park, not far from where the cast of “Jersey Shore” used to frolic.

“If she continues on the path, there’s a good possibility she’ll pass by New York,” said Chris Berger, President of OCEARCH, which tracks the shark via an interactive online map.

If the behemoth keeps heading north at her current clip of 40 miles per day, she’ll be in Long Island waters by Monday.

The big fish last swam through our neighborhood in January 2013, making a pit stop near East Patchogue, LI, to guzzle nutrient-rich water, Berger said. Not long after, she gave birth, he said.

The gestation period of a great white shark is every 18 months, so she may be headed to Cape Cod — where there are plenty of seals to eat — to “drop off a pup,” Berger said.

In the past, Mary Lee has steered clear of New York Harbor. But great whites have been known to swim right up to shore when hungry.

“Mary Lee goes where she wants — she has a mind of her own,” Berger said.”
