Meaning & origin

Tomasa is a distinctly feminine Spanish name, the counterpart of Tomás. First recorded in the United States in 1887, it experienced a peak in popularity around 1913. After a long decline, it has seen a modest resurgence since 2015, reflecting a revival of early 20th-century names. While it never ranked among the top names, its rarity adds to its charm. Tomasa is most commonly used in Hispanic communities, often honoring family traditions.

Tomasa is the Spanish feminine form of Tomás, which itself comes from the Aramaic name Te'oma, meaning "twin." The name was brought into use through the apostle Thomas, known as "Doubting Thomas." It has been used in Spanish-speaking cultures since at least the 19th century, though it remains relatively uncommon compared to its masculine counterpart.
