No.
From a writing standpoint, she was a spin-off character from a different earlier show, Hurcules:Legendary Journeys, which was just as fantastical/fictional. Her name is from root "Xenos", simply meaning stranger or foreigner.
There's no historical basis or analog for the character unless you want to stretch it to a Joan of Arc sort of heroine.
The Xena series is wholly fiction - their world an amalgamation of Greek Mythology mixed with bits of judeo-christian, Egyptian, medieval, and Roman era settings/costumes/stories. The pantheon of "Gods" in the series are just as loose, with Greek, Norse, and even Indian/Hindu deities. They encounter assorted characters from different eras separated by centuries, from Homer to Cleopatra to Caesar, and venture from China to Britain, Siberia to Scandanavia.
I always think of her as a representation of Atalanta, who was the only female to take part in the hunt for the Calydonian Boar.
