Meaning & origin
Sonja is a name of Slavic origin, specifically a Russian diminutive of Sofia, meaning "wisdom." It has been widely used across Scandinavia, Germany, and other European countries. In the United States, Sonja first appeared in records in 1906. The name saw its peak in 1938, when it was at its highest rank. However, it has been on a falling trajectory since 1986, and in 2025 it ranks around 3,903, with roughly 1 in 43,440 newborns receiving the name. Sonja has never been among the top 1,000 names in recent decades, but it retains associations with strong, classic European roots.
Sonja is a Russian feminine given name, a diminutive of Sofia (or Sophia), which itself comes from the Greek word sophia, meaning "wisdom." However, due to association with the Hebrew name Hannah (meaning "grace"), the name has been traditionally interpreted as "God is gracious." The name spread throughout Scandinavia and German-speaking countries in the 19th and 20th centuries.
