Hannes Einari Sula (29 June 1894 – 21 November 1955) was a Finnish-Canadian revolutionary who fought in the Finnish Civil War.

After the Battle of Helsinki, Sula was a member of a delegation sent to the Murman Railway to organize Red troops in the north.

With Aarne Orjatsalo and August Wesley he formed an opposition against the pro-Bolshevik Verner Lehtimäki, the Finnish commander of the Murmansk Legion.

As the Murmansk Legion was disbanded, Sula was one of the legionnaries the Finnish Government banned of returning Finland despite the amnesty.

He was also a newspaperman in the Finnish-Canadian Metsätyöläinen, published by the Lumber Workers Industrial Union of Canada, and Vapaus.
