Iljan is a ♂ male name.
Iljan is probably a variant of the name Ilian. Ilian is a Swedish variant of the name Aegidius, but also a short form of Maximilian and Elijah. Besides, Iljan is a short form of the Slavic name Smiljan.
Iljan means “shield-holder” and “young goat” (from Aegidius), “greatest” (from Maximilian) and “my God is Yahweh” (from Elijah). Deriving from Smiljan, Iljan means “Helichrysum plant” or “everlasting plant” and “catsfoot”.
