Coat of arms of the Székelys

The coat of arms of the Székelys (Hungarian: Székely címer; Romanian: Stema secuilor) is the coat of arms used by the Hungarian Székely community of Romania. It is a blue coat of arms with a golden eight-pointed "sun-star" and a silver crescent moon, both perceived as ancient Székely symbols. Being designed by Ádám Kónya, the Szekler National Council adopted it in 2004 and is since then a symbol for the Székely people.

It is argued that the symbols of the coat of arms are traditional symbols of the Székelys. The crescent moon and sun have been used since at least the 15th century in Transylvania. However, the use of a "sun-star" as Kónya has defined it is controversial as it does not comply with heraldic rules.
