This may finally flush away that “Amber Turd” nickname.

The British judge who ruled that Johnny Depp repeatedly beat ex-wife Amber Heard also closely analyzed shocking claims that she defecated in their marital bed — ruling that the offending turd likely came from one of her pet pooches.

High Court Judge Andrew Nicol spent almost 600 words of Monday’s judgment analyzing the headline-grabbing incident that led to Depp giving his now-ex-wife the gross nickname — and finally dumping her.

Under a section headlined “feces on the bed,” the judge said that Depp insisted the supposed poop attack was relevant because it “led him to conclude that his marriage to Ms. Heard could not continue” and sparked one of their many fights.

“For what it is worth, I consider that it is unlikely that Ms. Heard or one of her friends was responsible,” the judge concluded of the poop, photos of which were shown in court as evidence.

Nicol noted that it happened when Depp was away, meaning “it was Ms. Heard who was likely to suffer from the feces on the bed, not him.”

“It was, therefore, a singularly ineffective means for Ms. Heard or one of her friends to ‘get back’ at Mr. Depp,” he wrote.

He also noted evidence that one of Heard’s dogs, Boo, “had an incomplete mastery of her bowels after she had accidentally consumed some marijuana.”

Heard, 34, has long denied being the mystery pooper.

“This accusation is completely untrue and has been designed purely to humiliate Ms. Heard,” a spokesperson for Heard previously told The Post.
