Isidore Heath Campbell wants to legally become a Hitler.

The New Jersey father — who first made headlines in 2008 when he unsuccessfully tried to have a birthday cake for his then-7-year-old son inscribed with “Happy Birthday Adolf Hitler” — has filed paperwork to change his last name to Hitler, NJ.com reports.

A hearing has been scheduled for Campbell, who was featured in the documentary “Meet the Hitlers,” on March 24 in Hunterdon County, according to court documents.

Campbell was among several people featured in the film that examined the “relationship between names and identity, by exploring the lives of people who are linked by the name ‘Hitler,’” according to IMDB.com.

“My son is Adolf Hitler Campbell,” he said in the film’s trailer. “I named him — big deal. Does that make it OK for them to come in and steal your children?”

Days after Campbell’s birthday cake request went viral, he and his then-wife, Deborah, would lose parental rights to his nine children.

Campbell was sentenced to 180 days in jail and two years of probation last year under a plea deal for charges of resisting arrest and obstructing justice in connection to a domestic violence incident on Oct. 19, 2015, NJ.com reports.

Campbell, who fled to Pennsylvania before police arrived, was later charged with aggravated assault. He was arrested by police in Shippensburg, Pa., last March and was sent back to New Jersey after waiving extradition.

Campbell was required to undergo a psychiatric evaluation with an assessment for batterer’s counseling, NJ.com reports.

In 2013, the self-professed Nazi walked into the Hunterdon County Courthouse wearing a Third Reich uniform, black boots and a swastika armband to petition a family court judge to let him see his youngest son, Heinrich Hons Campbell, who was removed from his custody after the boy’s birth in 2011. He was accompanied by a woman in Nazi garb who was a fellow member of the pro-Nazi group Hitler’s Order.

“Prisoners get to see their children, murderers get to see their children. What’s so horrible about being a Nazi?” Campbell told The Post after the hearing. “I just want to be a dad. I just want to prove I’m a good father, because I am . . . So what if I’m a Nazi, who cares?’’

State officials said they removed the boy because of previous violence in Campbell’s home after an anonymous abuse claim was made to local police. Campbell, however, claimed he was unfairly targeted due to the names he chose for his children and denied abusing them.

Officials from the state Division of Youth and Family Services had previously placed Heinrich’s older siblings — Adolf Hitler Campbell, JoyceLynn Aryan Nation Campbell and Honzlynn Jeannie Campbell — in foster care. Court papers indicated Isidore Campbell refused to follow an order to seek counseling because the “psychologist was Jewish.” He later lost an appeal of the state’s decision in 2014, MyCentralJersey.com reports.
