Meaning & origin
The name Tomasz, ranking 12,008th in the U.S. in 2025, is a distinctly Polish form of Thomas. It peaked in popularity in 1995, and since then its usage has been falling, reflecting broader trends in immigration and naming preferences. Approximately 1 in 341,615 boys received the name in 2025. While rarely ranking among top U.S. names, Tomasz remains a strong cultural identifier for Polish-American families, with a classic sound that pairs well with traditional Polish sibling names.
Tomasz is the Polish cognate of Thomas, derived from the Aramaic name Te'oma, meaning 'twin'. Introduced to Poland via Christianity, it has been in use since the Middle Ages and remains a classic Polish name.
