The 2015 US Open finalist had, as recently as this month, spoken of her uncertainty over whether she would bring the curtain down on her career.
However, Vinci published a lengthy statement via Twitter on Monday to confirm that she will be sticking around, for one more season at least.
“I am aware that the general level of tennis is remarkably high and I will need to give my best in every match,” she wrote.
“But I feel I still have the desire and enthusiasm to do something good in what is maybe the thing I do best, playing tennis.
“In a few days I will return to training to better prepare for 2017.
“And now you start to wonder if this will be my last year!”
