Meaning & Origin
A diminutive of the female given names Antonina or Antonia, from Russian
Tonya is a girl's and boy's baby name of Russian origin, a diminutive form of Antonina or Antonia — from the Roman family name Antonius, meaning 'priceless' or of uncertain Etruscan origin. It entered American use through Eastern European immigration and became popular in its own right.
Tonya peaked in the U.S. top 50 around 1972–1977. Figure skater Tonya Harding gave it a complicated cultural moment in the 1990s, but the name itself is simply warm and direct — a confident, no-nonsense choice.
