Rännäri Stadium (Finnish: Rännärin pesäpallostadion), known as MiiluAreena for sponsorship reasons, is a pesäpallo stadium located in Raahe, Finland. Since its opening it has been the home field of the Pattijoen Urheilijat, a Superpesis team.

The Rännäri Stadium is one of the favourite fields of players hitting the 2-side. On a bouncy field, the bounces rise high and the volume of situations and home runs are high. One of the special features of the field is the wind blowing from the Gulf of Bothnia.
