Harvey Weinstein won’t face trial for a fourth time on charges of allegedly raping actress Jessica Mann in 2013 — after the accuser opted not to go through the grueling process of testifying.

“It was clear to me at this last trial, I can no longer go through this,” Mann, 40, said in a letter read aloud during a hearing in Manhattan Supreme Court Thursday morning.

“It has put me through more harm than good,” Mann added of her experience on the witness stand.

Prosecutors’ decision not to retry the disgraced 74-year-old ex-Miramax boss comes after a jury failed to reach a unanimous verdict on Mann’s allegations for the second time at a trial this May.

“To be clear, we believe Ms. Mann’s account and her credibility as a witness,” Manhattan DA Alvin Bragg said in a statement.

“This has been an extraordinarily taxing ordeal for her, and she has never wavered while testifying in front of two grand juries and three trial juries over the course of eight years. We thank her for her honesty and her tremendous bravery.”

Weinstein, who is being held without bail on Rikers Island, still faces up to 25 years in prison when he’s sentenced on Sept. 23 on his separate conviction for sexually assaulting Miriam “Mimi” Haley, a former TV production assistant.
