USS Alhena (AK-26) was a United States Navy cargo ship. Bethlehem at Sparrows Point built her. She was launched on 18 January 1941 and commissioned on 15 June 1941.
The designation AK-26 marked her as a cargo ship, a hull whose work was to carry freight for the fleet.

Her unloading ran from 7 August through 9 August 1942. On the night of 29 September 1942 a torpedo from I-16 hit Alhena. She remained afloat. On 26 November 1942 the Navy redesignated her AKA-9.
