A 79-year-old woman — disabled years ago when she suffered a stroke — died in a blaze inside her Brooklyn home Saturday evening, officials said.

The one-alarm fire broke out on the first floor of the two-story house on Quincy Street near Throop Avenue in Bed-Stuy at around 6:45 p.m.

Victim Elizabeth Mahone was pulled from the burning home where neighbors said she’d lived for decades, but was pronounced dead on the scene.

The fire was under control by 8 p.m.; its cause remained under investigation Saturday.

Mahone’s charred and bent walker lay on the lawn outside the three-story brownstone as her neighbors recalled her as a retired US postal worker who they’d often see, pre-stroke, tending to her little backyard garden.

“She was a professional. She was a nice lady. She a very nice lady,” said longtime next-door neighbor Valerie Waller.

“Oh my God,” added Waller, who’d known the victim since 1969. “This has been such a shock.”

Waller’s son, Jermaine James, 39, had called 911 and rushed over to Mahone’s home with a garden hose at the first smell of smoke, she said.

“My son came out and tried to do what he could do,” she said. “But it was just too late,” she said.
