Dejected Eagles fans took to the streets of Philadelphia after their team’s devastating Super Bowl loss to the Kansas City Chiefs — hurling profanities, lighting fireworks, and clashing with cops Sunday night and early into Monday.

Broad Street looked like a sea of green as heartbroken Philly fans climbed traffic lights and chanted “F— the Chiefs!” after the Eagles’ stunning 38-35 defeat, according to videos posted to social media.

Police issued warnings to rowdy fans, some of whom were seen igniting fireworks on the ground, climbing greased poles and jumping onto bus shelters, Fox News reported.

“The thing is, win or lose… philly still gonna be philly bc ITS A PHILLY THING,” Twitter user @Annie_Wu_22 wrote, sharing footage of a crowd yelling obscenities.

At one point, someone threw a section of a fence, but it did not hit anyone, ABC 6 reported.

Dozens of police officers and SWAT team members stood ready in riot gear as they ordered the revelers to disperse over a speaker.

Police deployed smoke bombs around 11 p.m. to break up the crowds and get people to head home, videos posted to Twitter show.

Bicycle cops and a group of people also clashed along Broad Street, NBC Philadelphia reported.

Some fans were seen being taken into custody late Sunday.

Two people were slapped with misdemeanor charges and 11 others were cited for disorderly conduct, police told The Post, adding that one officer suffered minor injuries in the mayhem but did not seek medical treatment.

Earlier in the day, wild fans overturned a car on a crowded street near Temple University before the big game had even started.

People remained mostly peaceful on Broad Street, according to Fox 29, and the crowd left the streets between 11 p.m. and midnight.

The diehards had begun partying on the streets while the Eagles were still ahead — before a controversial holding call late in the game, which paved the way for the Chiefs’ final field goal that earned them their third Super Bowl title.

After the game, Eagles cornerback James Bradberry admitted to holding Chiefs wide receiver JuJu Smith-Schuster on the game-winning drive.

“I’m so disappointed at that call, (Bradberry) barely touched him, at the end of the game, you’re gonna make a call like that? The Super Bowl is going to be decided on a call like that?” one fan said, according to Fox 29.

Birds fans continued to cheer on their team despite the last-minute upset as confetti rained down and fireworks illuminated the sky.

“Not happy,” Grumpy’s Tavern manager Keith D’Alfonso grumbled as patrons yelled expletives, the Philadelphia Inquirer reported.

At Reale’s Sports Bar & Grill on Frankford Avenue, Ashton Crawford, 31, stared glumly at the TV as the Chiefs celebrated their victory.

“I’m just torturing myself. I thought we had it. I thought we would be outside in the streets, celebrating,” he said.

On Broad Street, Jamel Fanning, 40, waxed philosophical amid the disappointment.

“You’re always gonna have ups and downs anytime you play this game,” Fanning told the Inquirer. “We still got to support our team. We don’t drop support because they lost.”

Around midnight Monday, police lined up on Broad Street to clear the area near City Hall, and crews from the Department of Public Property later collected and stacked fencing onto trucks.

Philadelphia police had prepared for a chaotic scene following the Super Bowl given the notoriously rambunctious Birds fans’ past behavior.

Last month, fans celebrated the Eagles’ NFC Championship game win over the 49ers by climbing light poles and crosswalk lights and standing on bus stop shelters.

In 2018, authorities famously greased light poles around the city, when the Eagles beat the Patriots in the Super Bowl, but it wasn’t enough to keep enterprising fans from climbing them.
