Meaning & origin
Zosia, a Polish diminutive of Zofia (Sophia), has been gaining steady use in the United States since the early 2000s. First recorded in U.S. data in 1997, it has risen from obscurity to a rank of 4,067 in 2025, with frequency of about 1 in every 45,922 births. Its peak popularity came in 2022, likely influenced by actress Zosia Mamet (known for Girls). The name has shown a consistent upward trajectory since 2002, and its top state is New York, reflecting its appeal in culturally diverse urban areas. Despite its Slavic roots, Zosia fits well among modern short feminine names like Mila and Lena, offering a distinctive yet accessible alternative to Sophia and its variants.
Zosia is a Polish diminutive of Zofia, which is the Polish form of Sophia, ultimately from Greek sophia meaning 'wisdom'. While a common nickname in Poland, it has gained use as an independent given name internationally, notably after actress Zosia Mamet brought it to wider attention in the 2010s. Its usage in the United States has been rising since the early 2000s.
