Alena Steam Products Co. was an American automotive manufacturer based in Indianapolis, Indiana, founded in 1922. The company aimed to produce steam-powered vehicles, including cars, trucks, and tractors.

Despite its ambitious plans, Alena Steam Products Co. only succeeded in completing two prototypes of a steam-powered tourer featuring a 2-cylinder engine. The announced price for these prototypes was $2,750. The company did not progress beyond these initial models, and as a result, it remains a relatively obscure name in the history of automotive manufacturing.
