Originally an Italian diminutive of Antonia, it is now used strictly as an independent given name both in Italy and abroad. It is especially popular in Italian diaspora communities. It is currently the 6th most popular female name in Chile, (2010) and the 21st most popular in Argentina (2009).
Another form of the name is the Croation, and occasionally, Spanish form Antonela.
In fact, Antonela is currently the 80th most popular female name in Croatia, (2010).
The name is borne by Italian-Argentine actress, Antonella Costa (b.1980).
