A runaway bull sparked a “high steaks” chase in Queens — hoofing it through a housing project and into one neighbor’s back yard — before cops nabbed him Tuesday, cops and witnesses said.

The farmyard troublemaker took off to explore the urban jungle around 10 a.m. in Jamaica and was finally shot with a tranquilizer dart and captured in the back yard of a home on Marsden and 168th streets around 12:30 p.m., according to police and stunned neighbors.

“I saw this big black thing running with all this drool from its mouth like it was ready to eat something alive,” said neighbor Kenneisha Cassan, 27. “I busted a U-turn and I’m like, ‘I’m going where this is going, because I’ve never see anything like this in my life.’”

The bold bovine first bolted to a housing project playground to escape police, who swarmed the scene, Cassan said.

“A least four or five cops tried to back him in in the playground, and he wasn’t having it,” Cassan said. “He was like, no, I’m not trying to get killed today.”

A total of 10 police vehicles rushed to wrangle the animal, which was caught on camera running — tongue out — down a quiet residential street Tuesday morning.

A witness, Jimmy King, 54, said the barnyard beast nearly mowed him down.

“He came straight at me,” King said. “He was no more than 3 feet from me.”

Police shot the raging bull with a tranquilizer to calm him and also injected the animal with a syringe of xylazine, a drug used for sedation, which knocked the bull out for at least an hour, sources said.

Officials plan to transport the bull to a nearby ASPCA, sources said.

The animal escaped from a slaughterhouse on Beaver Road, a police source said.

“It looked like he was trying to get away from the slaughterhouse. He didn’t want to get killed. I don’t blame him,” said another witness, Giovanni Snow.
