An unhinged Georgia mother threatened to kill a group of students for allegedly bullying her 11-year-old son at school, police said.

Cirea Oliver, 29, remains held without bail after cops in Gainesville said she took her maternal instincts to another level by warning his alleged tormentors that she would shoot them if they didn’t stop, WSB-TV reported.

“I’ma beat your ass if you keep f–king with my son,” Oliver said in the 40-minute Facebook Live post, which has since been removed. “I’m gonna tell you now, I’m putting a bullet through all y’all motherf–king heads.”

At another point, Oliver warned the parents of the alleged bullies that she’d be responsible if one of their children came home from school with a “black eye,” according to the shocking footage.

“Ain’t nobody calming down,” Oliver’s epic rant continued. “These kids, it’s a lack of parenting and it’s a lack of f–king teachers in the school system that give a f–k about these kids.”

Oliver, who was arrested Monday at Gainesville Middle School after posting the video earlier in the day, has been charged with making terroristic threats and acts, jail records show. She also had two outstanding unrelated warrants for her arrest, WSB-TV reported.

A message seeking comment from Gainesville police was not immediately returned early Thursday. But a spokeswoman told the station that any threat of violence — especially one directed against children — is taken “very seriously.”

Oliver’s mother, meanwhile, defended her daughter when approached by a reporter.

“She is a good mother,” the woman told the station. “She was right. I’d do the same thing.”

But, pressed further, Oliver’s mother acknowledged that she was wrong to threaten to shoot her son’s alleged bullies.

In a statement to The Post, school district officials confirmed Oliver was arrested on school grounds after they were alerted Monday to the video.

“While we cannot release information pertaining to specific student situations, the district utilizes established procedures for bullying and suicidal ideation,” the statement reads. “Our primary focus is to ensure that appropriate resources and services are available to students whenever needed.”
