The ghosts of New York’s past are going to roll in their graves.
Brooklyn’s historic Green-Wood Cemetery is allowing joggers to tread on the dead for the first time ever because President Obama’s visit will shut down nearby Prospect Park on Friday.
The famed boneyard, where artist Jean-Michel Basquiat, composer Leonard Bernstein and the notorious Boss Tweed are buried, will open its gates to the athletic set from noon until 6 p.m.
The move is for one day only, and runners are being urged to steer clear of mourners.
“Joggers are asked to show proper respect for those who are grieving or visiting the final resting places of family members and loved ones,” the cemetery said in a press release Thursday.
Visitors to Green-Wood — which is about seven blocks from Prospect Park — called the move dead wrong.
“There are other places to run. It’s not appropriate. I wouldn’t have let them in,” said Vito Scalogna, 55, of Bensonhurst, who was visiting his parents’ grave site.
Obama’s visit to Pathways in Technology Early College HS in Crown Heights will shut down nearly all 538 acres of Prospect Park — and some surrounding streets.
Richard Moylan, president of Green-Wood Cemetery, said the graveyard opted to bend its no running rule because this is prime marathon training time.
“Green-Wood is an active cemetery . . . with the New York City Marathon right around the corner, with thousands of Brooklynites in training for the race . . . we decided that lifting the prohibition on running for one day was the right and neighborly thing to do,” he told The Post.
Joggers are encouraged to enter the cemetery at an entrance on 25th Street and Fifth Avenue, a cemetery official said.
Cyclists aren’t allowed for safety reasons.
Roughly 600,000 people are buried at the sprawling historic landmark, which served as Brooklyn’s major greenspace before Prospect Park was built.
Many famous New Yorkers who died during the second half of the 19th century are buried in the 478-acre cemetery — once a major tourist destination that features a Civil War Memorial.
The Prospect Park shutdown also angered Orthodox Jews in Crown Heights who say the visit closes off key shopping streets before the Sabbath sundown, including bustling Kingston Avenue.
Friday afternoon is a major shopping time for the Orthodox, who are forbidden to shop or do errands after nightfall.
“He could have come Monday, Tuesday, any day. Why did he have to pick Friday?” grumbled one resident.
Others called it bad for business.
“Friday, it’s a lot of business being done. It makes no sense. I’ll lose 50 percent of my prepared food,” said an owner of House of Glatt, who declined to give his name.
