New York City was buzzing Wednesday night as Knicks fans rejoiced in bars, bodegas, watch parties, city streets, and their own living rooms across the five boroughs after the team’s stunning comeback to win Game 4 — with the NBA championship now just one victory away.

The Knicks stormed back in the second half with the biggest comeback in NBA Finals history to steal Game 4 at Madison Square Garden with a 107-106 win and take a 3-1 series lead over the Spurs.

The Big Apple became one big celebration following the orange and blue’s miraculous rally within the final seconds to clinch the game.

New Yorkers set off fireworks, erupted in booming cheers and chants of “Knicks in Five,” crazily honked, hugged each other, danced in the streets and sang in the subways.

“It was electrifying. Oh my God, words can’t describe it,” Frederick Cassie, 21, of Flatbush, told The Post outside Midtown bar Lady Wilde’s. “This was historical.”

The feeling was electric in all corners of the city.

One joyous fan climbed up the pole of a bus stop sign on Seventh Avenue and did a backflip off it to raucous cheers from hundreds in the street. In Central Park, complete strangers huddled beside each other while watching the game on cellphones. Staten Island’s skies erupted in fireworks, while crowds lined up on Smith Street in Carroll Gardens, chanting “OG, OG, OG!” in reference to Knicks player OG Anunoby’s dramatic game-winning shot.

“Anything can happen in a New York Minute. What the F just happened? Knicks in six,” said Randy Sanchez, 28, from the Hudson Valley.

“I feel so great right now. I’m actually so lit. 
This is amazing. I can’t wait for the next game,” Layla David, 19, said outside the Central Park watch party.

The Knicks can clinch their first NBA title since 1973 with a victory Saturday in San Antonio.

“After tonight, I’m convinced that game five, we are taking it, they’re gonna win in San Antonio, and they’re gonna bring that championship trophy back to New York City, and that parade is gonna be insane,” James Egiziaco, 44, said. “And I’m taking off of work, and I’m gonna be there.”

Madison Square Garden remained packed after Game 4 ended with hometown fanatics too thrilled to leave the arena, clips showed.

“It was the largest comeback ever. If any team could do it, the New York Knicks can. They’re going to win the championship,” Tommy Connors, 19, of Queens, said a few blocks up from the Garden. “Wemby [San Antonio villain Victory Wembanyama] folded under pressure. He couldn’t handle the Garden. He’s crying right now.”

For longtime Knicks faithful, the historic win was even more special.

“I’ve been a fan since ’92. We haven’t won a championship since ’93. This day is a day in history,” Steven St. Pierre, a 40-year-old actor and filmmaker. “We are here to witness it. Let’s go next. Jalen Brunson, the king of New York — he’s getting a statue outside the Garden. Let’s talk about it. Let’s go.”

The Knicks will face the Spurs in San Antonio on Saturday for the chance to win the finals once and for all.
