Tania is a pet form of Tatiana, the name of a Roman family and an early Christian martyr, whose meaning is uncertain and usually explained as "from the Tatius clan" or "fairy queen" after Shakespeare's Titania. It became an independent name in Russia and spread through Latin America and Europe. Tania ranked number 460 in the United States in 2000 and peaked at number 412 in 2002, then faded with other 1970s favorites to number 2050 in 2025.
