The wife of the 1960s actor who played “Tarzan” was allegedly stabbed to death at the couple’s California home by their son — who was then fatally gunned down by police, cops said Wednesday.

Cops discovered the body of Ron Ely’s longtime spouse, Valerie Lundeen, after a caller reported a domestic violence dispute at the upscale Santa Barbra home on Tuesday night, according to the Santa Barbara County Sheriff’s office.

She had been stabbed “multiple times,” police said.

Cops then found her 30-year-old son, Cameron Ely, on the property and fatally shot him after he “posed a threat,” the department said.

The actor, 81, was not harmed and is not considered a suspect, according to local reports.

A friend of Lundeen — a former Miss Florida and mother of three — was furious and heartbroken over her killing.

“I’m so mad,” Dale Goodman, of Dania Beach, Florida, told The Post.

“It’s just so sad. She was an unbelievable unperson — so vibrant,” he said, adding that she was his mother’s “best friend.”

In audio obtained by TMZ, an “elderly gentleman” at the scene could be heard saying his son was involved in the incident.

Meanwhile, deputies who opened fire on the suspect will be placed on administrative leave, according to police. No deputies were injured.

Ely played Tarzan from 1966 to 1968, and stared in “Fantasy Island” along with the 1975 film “Doc Savage: The Man of Iron and Bronze.”

He also hosted the Miss America pageant in the 1980s.
