Prince Andrew has refused to cooperate with the feds in their ongoing probe into Jeffrey Epstein, authorities said Monday.

Manhattan US Attorney Geoffrey Berman took the rare step of telling reporters at a press conference outside Epstein’s former Upper East Side mansion that prosecutors had reached out to the embattled royal, who has been accused of having sex with at least one teen Epstein trafficked — and that the prince has yet to agree to a sit-down.

“The Southern District of New York and the FBI have contacted Prince Andrew’s attorneys and requested to interview Prince Andrew, and to date, Prince Andrew has provided zero cooperation,” Berman said.

The top prosecutor said he was revealing Andrew’s refusal to cooperate because, after all, the prince “publicly offered, indeed in a press release, to cooperate with law enforcement investigating the crimes committed by Jeffrey Epstein and his co-conspirators.”

Berman appeared to be referring to a statement issued by the Duke of York in November in which he said, “I am willing to help any appropriate law enforcement agency with their investigations.”

A royal source told The Post in an e-mail Monday, “This issue is being dealt with by The Duke of York’s legal team. Buckingham Palace will not be commenting further on this particular matter.”

Andrew has denied any wrongdoing in his relationship with the convicted pedophile.

Epstein died behind bars in Manhattan in August while awaiting trial for sex trafficking. But Berman said the investigation into the perverted financier’s alleged abusive sex network is continuing because “Jeffrey Epstein couldn’t have done what he did without the assistance of others.

“And I can assure you that the investigation is moving foward,” the top prosecutor said.

The press conference was held to tout a new state law designed to make it easier for child-sex-abuse victims to sue.

One of Epstein’s main accusers, Virginia Roberts Giuffre, has said she had sex with Andrew three times, including when she was 17, at the behest of Epstein.

The prince famously denied the accusation in a disastrous BBC interview in November, making seemingly outrageous claims including that he couldn’t have sweated as much as Giuffre said because of an old war wound — even though photos through the years indicated that he regularly heavily perspired at that time
