Kestutis

Kestutis, spelled Kęstutis in Lithuanian, is a masculine given name of Lithuanian origin. It has a long history in Lithuania and is still used today among Lithuanians and their communities abroad. The name is traditionally associated with the medieval Gediminid dynasty and is most commonly linked to Kęstutis, a 14th‑century Lithuanian duke who played a prominent role in the politics and affairs of the Grand Duchy of Lithuania. In 1382 he was captured by the Teutonic Knights at Krevo and died in captivity, a event that had lasting influence on the region’s history.

The exact meaning and etymology of Kęstutis are not definitively established, as with many ancient Baltic names. It is regarded as a native Lithuanian name rather than a loanword, and its use reflects local naming traditions rather than external influence. In non‑Lithuanian contexts, the name is frequently rendered without diacritics as Kestutis.

In contemporary usage, Kęstutis remains a traditional and relatively common given name in Lithuania. It is used across generations, and various spellings or transliterations may appear in international settings or English‑language sources. While the spelling with diacritics is preferred in Lithuania, the non‑diacritic form Kestutis is widely recognized for global communication.
