Meaning & origin

Tomi is a name with multiple cultural roots, most notably as a Japanese short form conveying wealth and fortune, and as a Finnish diminutive of Thomas. In the United States, it has been used primarily for girls, with recorded usage dating back to 1916. Its popularity peaked in 1977, and after a period of decline, it has been on a rising trajectory since 2011, currently ranking 5,917. The name is rare, with only about 1 in 80,363 newborns receiving it in the latest year. Despite its low frequency, its upward trend suggests a growing appeal, possibly driven by the trend toward short, internationally flavored names. Tomi is not strongly associated with any particular state, and its usage remains scattered across the country. The name's ambiguity in origin adds to its modern, versatile character, making it a distinctive choice that connects to both Japanese elegance and European tradition.

Tomi has multiple possible origins. In Japanese, it is often a short form of names like Tomiko or Tomomi, where the element 'tomi' means 'wealth, fortune' (富). In Finland, Tomi is a masculine diminutive of Thomas, while in English-speaking countries it is sometimes used as a feminine nickname for Thomasina or as a given name in its own right. The name has seen modest use in the United States since the early 20th century, with a peak in the 1970s.
