尼古拉（源自于希腊语：Νικόλαος），也译为尼古拉斯、尼可拉斯、尼古莱、尼科洛、尼各老、尼阁，是一些西方语言中常见的名字。

Nicholas or Nikolas or Nicolas or Nickolas is a male given name, derived from the Greek name Νικόλαος (Nikolaos), a compound of νίκη nikē 'victory' and λαός; laos 'people', that is, victory of the people. The name became popular through Saint Nicholas, Bishop of Myra in Lycia, the inspiration for Santa Claus. The customary English version of spelling "Nicholas", using an "h", first came into use in the 12th century and has been firmly established since the Reformation, though "Nicolas" is occasionally used.
