A FedEx deliveryman was grazed by a stray bullet while working in the Bronx on Thursday, police said.

Shots rang out after two men on a moped tried to rob a building employee’s moped near 950 Jennings St. around 11:45 a.m., according to police.

The suspects failed to steal the would-be victim’s moped and as they fled on their own two-wheeler, they fired several shots — one of which grazed the 20-year-old on-duty FedEx employee in the back, cops said.

The FedEx worker, who was the unintended target, was taken to Lincoln Hospital in stable condition.

“We are grateful our team member was not seriously injured,” a FedEx spokesperson told The Post.

No arrests have been made, cops said.
