A baby girl was left abandoned in her overturned stroller in Times Square by her heartless father late Tuesday night — with cops now looking for the deadbeat dad, police and sources said. 

The one-year-old was left alone and toppled over near West 44th Street and Broadway at around 11 p.m.

Her dad, who is homeless, had ran off with her in the stroller after a spat with the tot’s mom, law enforcement sources said.

After the stroller tipped over, he just walked away without helping the child up, the sources said. Police soon arrived and rushed the child to Greenwich Village Hospital, where she is in stable condition

“That’s horrible,” Chioma Ortiz, a mother of two who works for the Topview sightseeing company. “I’m ashamed of that parent.

“People can’t have babies and you are leaving the one God gave you out here,” Ortiz said. “People go through hell just to have one. That’s crazy. I’d never do that. Never.”

Vikas Upendra, a visitor from Atlanta, was pushing a double stroller with her two youngsters when she heard about the baby.

“That’s very irresponsible,” she said. “[The father] obviously needs help. Maybe he’s mentally unstable too. I don’t know how somebody could do that, especially late at night, and yesterday was a cold day.”

Times Square food vendor Nader Riko said he showed up for work Wednesday morning to learn that his coworker had witnessed the heartless incident the night before.

“Shocked. I feel sad, sad. It’s a baby,” he said. “I have [a] baby too, 14 months. I love my baby.” 

No arrests have been made and the investigation is ongoing, cops said.
