Natashia is of Greek origin and means "born on Christmas Day". It is a variant spelling of Natasha, which itself comes from the Russian feminine diminutive form of Natalia, meaning "birth on Christmas". The name gained popularity in the English-speaking world through Leo Tolstoy's novel "War and Peace", where one of the main characters is named Natasha Rostova. Natashia shares its popularity with its spelling variant Natasha, but both names are relatively uncommon. They are typically associated with individuals who are strong-willed, intelligent, and independent, reflecting the character traits of the renowned Natasha Rostova. The name has also been used by celebrities such as actress Natasha Richardson and singer Natasha Bedingfield, further contributing to its recognition in popular culture.
The name Natashia experienced significant popularity from the late 1960s to the early 1980s, with a peak of 145 births in 1985. However, its usage has declined notably since then, with fewer than 50 births per year after 1992 and single-digit figures from 2005 onwards. As of 2013, there have been a total of 2631 babies named Natashia.
