Dena

Dena is a feminine given name, often a variant of Dina or Deena, which in turn derive from the Hebrew name Dinah. The form is used in English-speaking countries and appears in various cultural contexts as a personal name.

Dena'ina refers to an Alaska Native people of south-central Alaska. The ethnonym Dena'ina means "the people" in their own language, and the group historically inhabited areas around Cook Inlet, the Kenai Peninsula, and nearby regions. The name Dena appears in some historical or ethnographic texts as a shortened or Anglicized reference to the Dena'ina.

DENA commonly stands for Deutsche Energie-Agentur, the German Energy Agency. Established to promote energy efficiency, renewable energy, and the modernization of energy systems, it serves as an advisory body and coordinating entity for energy policy implementation in Germany.

The term Dena may also occur in other contexts as a surname, a place name, or an acronym, depending on language and region. As with many short names and terms, its meaning is highly context-dependent.
