The Royal Crown of Serbia is a royal regalia that existed during the Serbian monarchy.

Regalia is the set of emblems, symbols, or paraphernalia indicative of royal status, as well as rights, prerogatives and privileges enjoyed by a sovereign, regardless of title. The word originally referred to the elaborate formal dress and accessories of a sovereign, but now it also refers to any type of elaborate formal dress. The word stems from the Latin substantivation of the adjective regalis, "regal", itself from rex, "king". It is sometimes used in the singular, regale.
