Two men were slashed in separate late-night scuffles across Manhattan, police said Saturday.

Just after midnight, a fight broke out at a Dunkin’ Donuts on 8th Avenue near 51st Street, officials said.

During the brawl, one of the men was slashed in the hand with a sharp object, police said.

He sustained a minor injury, while his attacker — described as a man with curly hair wearing a brown jacket — fled the scene.

Less than an hour later at about 1 a.m., a 25-year-old man was stabbed in the back of the neck during an argument on 2nd Avenue near East 5th Street in the East Village, cops said.

His assailant, believed to be a man in his 20s, ran off after the attack.

The victim was taken to Bellevue Hospital in stable condition, authorities said.
