Katleen

Katleen is a feminine name that represents a simplified variant of Katherine or Kathleen. While Kathleen has Irish roots as an anglicized form of Caitlín (Irish form of Katherine), Katleen emerged as a streamlined spelling that maintains the same pronunciation. Katherine ultimately derives from the Greek name Aikaterine, possibly meaning 'pure.' Katleen gained some usage in the mid-20th century but remains less common than its traditional counterparts. This variant offers the familiar sound and cultural resonance of Kathleen while potentially avoiding spelling confusion with its dropped 'h'. The name retains a classic, graceful quality while feeling slightly more modern in its simplified form. Nickname possibilities include Kat, Katie, or Lee.

Pronounced kat-LEEN.

As of October 2026, Katleen ranked #18734 in US births in 2009 SSA, peaked at #3015 in 1953.
