Eight people were hurt in shootings across New York City overnight, including two city Corrections officers struck when someone opened fire on a Queens nightclub, police said.

A man who had been booted from the Showtime Bar and Lounge on 101st Avenue in Richmond Hill around 1:30 a.m. allegedly shot into the club after he’d been ejected, an NYPD spokesman said.

His two victims — a 31-year-old man and 29-year-old woman — were not known to the suspect and not his intended target, cops said.

The man was struck in the left hand and underwent surgery, while the woman was hit in the left foot, according to cops and the Corrections Officers’ union.

Police said the shooter fled and has not been arrested.

The injured officers were off duty and at a party, said Benny Boscio, head of the Correction Officers Benevolent Association, in a statement.

Two hours later, at a restaurant on the other side of Queens on Northern Boulevard in Jackson Heights, NYPD said a dispute led to two people being shot — a 20-year-old woman and 37-year-old restaurant employee.

Queens’ bloody Saturday morning followed a Friday evening that saw four separate shootings in the span of hours in Upper Manhattan and the Bronx.

The violence got underway early on Adams Clayton Powell, Jr. Blvd. in East Harlem, where a man wearing all black and a face mask fired shots and ran just before 7 p.m., according to NYPD.

No injuries were initially reported, until later in the evening when a 27-year-old victim of the shooting “hobbled” into Lincoln Hospital with bullet wounds to each leg, the spokesman said.

An hour after the East Harlem shooting, a man, 32, was shot in the left arm by two attackers on a scooter on Gun Hill Road in the Bronx, police said.

Fifteen minutes later, at 8:15 p.m., a woman was shot in the leg inside the lobby of NYCHA’s Betances Houses, NYPD said. A firearm was recovered at the scene and one person is in custody but has not been charged, according to the spokesman.

The evening’s fourth victim was a “highly uncooperative” man who cops said was shot in the left leg by an unknown perpetrator in Highbridge at around 11:40 p.m.

The man had a long list of prior arrests, according to police sources.
