The Italian woman said she and her husband Enzo were completely delighted with their first baby.
She told local media: "I have fulfilled my dream. The future does not scare me."
Surprisingly, Maria Rosaria did not have any reproductive treatment to ensure that she got pregnant.
Doctor Stefano Palmieri, who oversaw the birth at a hospital in the Castel Volturno commune in the Campania region in the south-western part of Italy, said: "It was a peaceful pregnancy."
"The lady did regular physical exercise up until her seventh month", he added.
Although this new birth may raise some eyebrows, the record is still held by an English woman who delivered her infant in 1887.
The woman had triplets at 62 and her boys, her 11th, 12th, and 13th children, were all brought into the world naturally.
The oldest person to ever give birth, records say, is 70-year-old Daljinder Kaur from India who had a baby with her 79-year-old husband Mohinder Singh Gill through IVF treatment.
