Can you believe these shmucks?!

Americans think New Yorkers are the biggest jerks in the country, according to a new survey — released just days before Christmas, no less.

The slap-in-the-face Business Insider study found 34.3 percent of the knuckleheads who responded believe Big Apple residents are the rudest in the US.

But many locals were too polite to respond to the diss Monday.

“F–k off!” one man told a Post reporter on 125th Street in Harlem when asked his opinion of the study.

Others thoughtfully questioned the methodology.

“Screw those people. Half the people probably haven’t been here!” said Carmen, 52, of The Bronx.

The study surveyed 2,000 adults online about the rudest city in the country. New York finished first going away.

Los Angeles came in a distant second with 19.7 percent.

Residents of Washington, DC, were rated the third-surliest, followed by Chicago, Boston, Detroit, Buffalo, Baltimore, Philadelphia and San Francisco.

Big Apple denizens, who spend life jammed against 9 million of their neighbors, are occasionally known to be short on patience with slow-walking tourists.

But visitors have long seen locals as the real problem.

When John Adams visited the city in 1774, he wrote in his diary: “With all the opulence and splendor of this city, there is very little good breeding to be found.”

“I have not seen one real gentleman, one well-bred man, since I came to town,” he continued, the New York Times once ­reported.

One man visiting from Florida on Monday agreed.

“Hell, yeah, everybody here’s an a–hole!” said the Floridian, who refused to give his name.

But Harlem man Sergio Villanueva, 26, suggested people in New Jersey are “much ruder” than New Yorkers.

Villanueva admitted New Yorkers can be rude, but insisted “it’s not personal.”

“Like, we don’t mean anything by it. It’s just the way we live,” he said.

“People got places to be, people to see. If I bump into you, sorry … but not really.”

Many others agreed that we’re just misunderstood.

Madison Scott, 27, moved from California to New York two years ago and insisted her new neighbors have hearts of gold.

“They’re not outgoing or super friendly but I remember I was on the train and some guy just started puking everywhere and a lot of people just started handing him napkins and water bottles,” she said, recalling one moment of Big Apple ­camaraderie.

“We’re kind of gruff,” added Long Island resident Rachael Sullivan, 21, “but we’re kind-hearted when you get to know us.”

In Harlem, Diane Powell, 36, dismissed rude New Yorkers as a “stereotype.”

“We’re just strong-willed,” she said.

But some admitted New Yorkers can occasionally get a bit short around the holiday season.

“People don’t care if you’re a child, old, elderly, they’re just like shopping. They’re just like, ‘Get out of my way,’ ” said Jessica ­Tejada, 26, of Manhattan while shopping at Macy’s with her family.

“New York is awful. We’re crowded. We’re like sardines because we’re just trapped together all the time.”

“On the holidays, workers are worse. I feel like they’re more rude, more nasty because they know people need it and people will tolerate it,” she added.
