Dewanoumi stable is a stable of sumo wrestlers, part of the Dewanoumi ichimon or group of stables. It has a long, prestigious history. Its current head coach is former maegashira Oginohana. As of January 2023, it had 19 wrestlers.

The stable has produced many successful sumo wrestlers and has been home to several Yokozuna, the highest rank in sumo. One of the most famous Yokozuna from Dewanoumi stable is Futabayama Sadaji, who achieved a record 69 consecutive wins in the 1930s.

The stable’s rise to prominence was due to the 19th yokozuna Hitachiyama, who transformed it from a minor stable when he joined sumo into a powerful recruiting house when he retired in 1914 and became its head coach. Under his leadership the stable produced several yokozuna and 20 other top division wrestlers. At its peak, the stable contained over 200 wrestlers.
