All around the world, Диена (Diena 
, Диена 
) is quite a rare unisex forename. The forename Диена is habitual in Indonesia, where it is a rare predominantly feminine, but scarcely masculine name, the Democratic Republic of the Congo, where it is a rare boy's name, and South Africa, where it is a rare female name. Very seldom, Диена is the last name as well as the forename.
