Hiukka Stadium (Finnish: Hiukan pesäpallostadion), known as Marjex Stadium (Finnish: Marjex Stadion) for sponsorship reasons, is a pesäpallo stadium located in Sotkamo, Finland. Since its opening in 1946, it has been the home field of the Sotkamon Jymy, a Superpesis team.

The Hiukka Stadium is located in the centre of Sotkamo, right on the shore of Sapsojärvi. The former athletics field has been used almost exclusively as a pesäpallo haven since the mid-1990s. The field is known for its purple artificial grass and Hiukka's beach, where the ball can be thrown by mistake.
