One of Jeffrey Epstein’s accusers was in “mourning” when she heard about the pedophile’s death — but only because it meant he wouldn’t be held accountable for his crimes, she said in an interview aired Thursday.

Virginia Roberts Giuffre, now 35, has said that she was just a teenager when she was recruited as one of Epstein’s “sex slaves” and ordered to sleep with a rotating door of high-powered men, including the UK’s Prince Andrew.

When she heard the perverted financier had died in a Manhattan lockup on Aug. 10, Giuffre was in “shock,” she said in an interview for a special edition of “Dateline NBC.”

“I was in mourning,” Giuffre said. “Not because the world lost a monster, I wasn’t mourning the death of this man.

“I was mourning the death of my ability to hold this man accountable.”

Giuffre was one of six Epstein accusers interviewed on the program, a clip of which aired on NBC’s “Nightly News” Thursday evening.

They were part of a group of nearly two dozen Epstein accusers who shared their stories of abuse during an Aug. 27 hearing to dismiss the federal sex trafficking charges against the late multimillionaire.

In the episode, which airs Friday, the women said they believe the justice system failed them, in part because of the wrist-slap plea deal Epstein copped in Florida in 2008 that let him dodge federal charges — and continue preying on victims.

Palm Beach police chief Michael Reiter, who oversaw the original local investigation into Epstein, said he couldn’t explain how the system had failed on so many levels.

“There is no explanation. I didn’t believe it back then, I don’t believe it now,” Reiter said. “It’s just unfathomable to me.”
