A Big Apple straphanger was knifed in the stomach during an attempted robbery on a moving subway Tuesday – with the distraught victim initially screaming, “I got shot,” cops and witnesses said.

The victim, aged in his 30s, was stabbed on a southbound No. 4 train in downtown Manhattan at about 12:30 p.m., police said.

A horrified bystander told The Post the blood-soaked man, who managed to make it out of the Wall Street subway station before collapsing outside the famed Trinity Church, was screaming that he’d been shot.

“There was blood around his mouth and nose,” said Orin Davidson, a tour bus hawker, who called 911.

“He said, ‘I got shot’ and then he collapsed.”

“He was just moaning and groaning that he got shot,” Davidson added.

The masked perp, who was believed to be a teen, fled when the train pulled into the Wall Street station, according to law enforcement sources.

The station was briefly shut down as cops scoured the area for any sign of the attacker.

Blood could be seen spattered on the platform in the wake of the terrifying, midday attack.

The victim was treated at the scene before being rushed to Bellevue Hospital with non-life-threatening injuries, police said.

No arrests had been made, according to cops.

“It’s highly disturbing because nothing of that sort has happened here before,” Davidson said.

“Financial District? You don’t expect something like that to happen here.”

Robberies in the city’s transit system have been soaring of late, the latest NYPD data show.

There were 128 muggings on trains and buses as of April 5 — a 21% spike from the 106 on record during the same period last year.
