A man was slashed in the neck, leaving him in critical condition, during an argument over a parking space in Queens, police said Tuesday.

The 26-year-old victim was parking his vehicle outside CTown Supermarket near 123rd St. and Liberty Ave. in South Richmond Hill when the confrontation sparked off about 3:30 a.m. Saturday, cops said.

The driver of a double-parked GMC Terrain pulled up behind the victim, got out of the SUV and yelled “What the f— are you doing? Move your f—ing car!”, police sources said.

As the clash escalated, the SUV driver pulled out a weapon and slashed the victim in the neck, police said.

The victim got to Jamaica Hospital by private means and was in critical but stable condition.

“Recovery is going quite slow so far,” the victim told the Daily News by phone Tuesday.

The attacker got back into his SUV and drove off.

On Tuesday, the NYPD released photos of the suspect as he argued with the victim and asked the public’s help identifying him and tracking him down. He was wearing a gray sweatshirt, white T-shirt, gray sweatpants and white sneakers.

Anyone with information is asked to call Crime Stoppers at (800) 577-TIPS. All calls will be kept confidential.
