Kathleen

Where the name comes from

• Irish (English spelling)
  An Irish form of Catherine
  Caitlín
  Kathleen is the English spelling of the Irish name Caitlín. Caitlín is one of several Irish forms of Catherine. It has been used in Ireland since the 1100s.
• Old French / Middle English
  Everyday form of Catherine
  Cateline (Catheline)
  In medieval France and England, Catherine was usually said as Cateline. Caitlín is the Irish version of that everyday form.
• Greek (by way of Latin)
  Origin uncertain
  Aikaterinē
  Catherine traces back to the Greek name Aikaterinē. Scholars do not know what it originally meant. The popular meaning "pure" comes from an old link people made to the Greek word katharos, "pure." That link is why English added the "h" to Catherine about 500 years ago. Some older Irish name books give "pure" as the meaning, but modern dictionaries treat it as a folk belief, not the true origin.

Kathleen across traditions

• Irish. In Irish literature and nationalism, Cathleen ni Houlihan (Caitlín Ní Uallacháin) stands for Ireland itself. W. B. Yeats made her famous in his 1902 play Cathleen ni Houlihan. In it, an old woman who has lost her "four green fields" turns out to be Ireland. The play became a high point of the Irish literary revival.
• Christian. The name honors Saint Catherine of Alexandria. Legend says she was a learned young woman martyred about 1,700 years ago, though historians doubt she was a real person. Crusaders brought her story to Western Europe. An Irish name scholar wrote in 1923 that the name's popularity in Ireland owed most to Saint Catherine of Siena.
• Spanish and Latin American. Kathleen has no Spanish form of its own. Its Spanish counterpart is Catalina, the Spanish form of Catherine. Catarina also appears in Spanish and Portuguese.
• United States. Kathleen peaked in the 1950s, when it was the #15 name for US girls. It ranks #31 among all girls' names given in the US from 1926 to 2025.
