Boyko (name)

Boyko or Boiko (Cyrillic: Бойко, Polish: Bojko) is one of the most common surnames in Ukraine, which is also widespread in countries such as Russia, Canada, United States and other lands with a history of immigration from Ukraine.

It is also found in South Slavic countries, as a form of the name Бојан/Bojan (Boyan). The surname Boiko is also common amongst Ashkenazi Jews (amongst whom it is spelled as 'Boiko' or 'Boico'), and possibly it is a form of 'Boge', or 'boikil' meaning "quick". In Western Ukraine, it might originate from the name of a highlanders tribe.

It may also be a masculine given name in Bulgaria.
