Treasa

Treasa is a feminine name with Irish Gaelic origins, serving as the Irish variant of Teresa or Theresa. The original Greek name Therasia means 'harvester' or 'from Thera' (an island), though the name gained popularity through St. Teresa of Ávila. In Ireland, Treasa (pronounced TRAH-sa) maintains strong cultural connections while offering a distinctive alternative to more common Teresa forms. The name has moderate recognition in Ireland but remains relatively uncommon elsewhere, making it a unique choice in most English-speaking countries. Treasa carries a lyrical quality characteristic of Irish names, with a blend of strength and gentleness. For families with Irish heritage, it provides a way to honor ancestral roots while giving a child a name that stands out subtly from more mainstream options.

Pronounced TRAY-suh.
