An infant miraculously escaped unscathed Friday after falling out a third-story window of a Bronx apartment building, according to police.

The 1-year-old tumbled out an unsecured window of their Cypress Avenue and East 141st Street unit around 7 p.m., the NYPD said.

The baby was rushed to Lincoln Hospital, where doctors determined they were “uninjured at this time,” cops said.

Investigators are probing the case, but believe the fall was accidental.

The infant’s extraordinary survival comes just four days after a 4-year-old boy fatally plunged from a fourth-floor window in Brooklyn.

One week earlier, a 3-year-old girl was seriously injured after squeezing through a gap in a window with an air conditioner inside her Harlem apartment building and plummeting six stories.

The three falls are the latest in a string across the city this year — including the death of 9-year-old Miguel Ramos, who had been climbing on the couch inside his sixth-story apartment when he opened the window, lost his balance and fell out.
