A woman on a nighttime jog in Central Park on Monday was beaten, mugged and nearly raped — part of a disturbing robbery spike in the city oasis, police officials said Tuesday.

A man grabbed the 27-year-old victim from behind and dragged her into some bushes at East drive and East 107th Street at around 9:40 Monday night, sources said.

“I’m going to cut your throat,” the assailant said as he threatened to rape the woman, the victim told investigators, according to sources.

The creep rifled through the victim’s pockets, taking her iPhone and keys, before knocking her to ground and repeatedly punching her in the head and kicking her about the body, the sources added.

“She is thrown to the ground by a male, black, 30 [years old],” said NYPD Chief of Detectives Robert Boyce Tuesday, describing the suspect as “heavyset, scruffy beard with a dark jacket and an orange T-shirt.”

The man ripped her pants down to her ankles and tried to rape her, but could not get an erection, so he got up and walked away, according to the sources.

Moments later, the thug returned and kicked the woman in the head one last time before finally running off.

When the injured woman realized the man was gone, she ran to 110th Street and Lenox Avenue, where she called for help from two cops manning a command post at the park’s entrance.

The attack is part of a frightening trend. There were five reported robberies in Central Park for the 28-day period ending Sunday, up from just one during the same period in 2015. The statistics do not include Monday night’s attack on the jogger.

“We do want people to use our parks but you have to be aware of your surroundings,” said NYPD Commissioner James O’Neill. “If it’s late at night, take a partner if you’re going to go running.”

The NYPD announced Tuesday that it is beefing up its 24-hour presence in Central Park as a way to combat an uptick in robberies.

“[It’s been a] bad month for the park, but we’re deploying a lot of resources into that area,” Boyce said.

Overall crime in Central Park is down 17 percent for the year, but felony assaults are up — with six in 2016 through Sunday compared with 3 for the same period in 2015.

“Certainly, this spike concerns us and one crime is one crime too many,” said NYPD Chief of Department Carlos Gomez.
