The name Jovan is a boy's name of Slavic, Latin origin meaning "Jove-like, majestic". Jovan and discussed in our forums with posts like "What would you name a sibling to...?".
From the experts:
Jovan, the name of the supreme Roman deity, seems more extraterrestrial now -- and it's also firmly attached to a perfume label. Some parents may see it as a variation of Giovanni, the Italian for John. It is in fact the Slavic variation of John and may be an original way to honor an ancestral John.
