Dejan (Cyrillic: Дејан) is a South Slavic masculine given name, most common among Croatian, Macedonian, Serbian, and Slovene speakers. The name derives from the Slavic verbal root dějati meaning "to do" or from dějanĭje meaning "deed, action," reflecting an active, dynamic quality. Etymology The name is rooted in the Slavic element dej- (to act, to do), which appears in words such as Russian дело (delo, "deed") and Polish działać (to act).
