Alanna or Alana is a female given name and traditionally considered the feminine form of the name Alan. It is derived from the Gaelic or Celtic Languages meaning "rock" (ail), "beautiful" (àlainn), or "child" (leanbh). In Welsh, the similar word alawn means "harmony" or "melody," which may also be connected. Additionally, Alana is a unisex given name in the Hawaiian Language, meaning "awakening". The name Alana may also be linked to Alauna, a Celtic river goddess worshiped in parts of ancient Gaul and Britain.
