Castelvetrano olives, known as Nocellara del Belice in their native range, is an olive cultivar from the Valle del Belice area of south-western Sicily. It is a dual-purpose olive, grown both for oil and for the table. It is used to make "Valle del Belìce" extra-virgin olive oil, which is pressed from a minimum of 70% Nocellara del Belice olives. As a table olive, it is a large, green olive with a mild, buttery flavor.
The Nocellara del Belice olive has two DOP protections: both Valle del Belìce DOP olive oil and Nocellara del Belice DOP table olives have protected status in the European Union.
Nocellara del Belice olives are grown primarily in Sicily, but also in India, Pakistan and South Africa.
