Northwestern Medicine Field at Martin Stadium - Chicago Stars

Lanny and Sharon Martin Stadium (currently known as Northwestern Medicine Field at Martin Stadium for sponsorship reasons) is an outdoor sports and recreation facility on the campus of Northwestern University in Evanston, Illinois. It is the home stadium of the Northwestern Wildcats soccer and lacrosse teams, as well as the current temporary home stadium of the school's football team during the construction of its new permanent stadium. The venue was enlarged in mid-2024 to accommodate the interim tenancy of the football program. In professional sports, the stadium serves as home venue for the Chicago Tempest of Women's Elite Rugby, and will serve as home for the Chicago Stars FC of the National Women's Soccer League in the 2026 season.

The venue is located along the shore of Lake Michigan on the northeast end of the campus, adjacent to several other university athletic facilities and the Kellogg Global Hub academic building. It is a component of the university's Lakefront Athletics and Recreation Complex, which also features Lakeside Field (a field hockey venue), Norris Aquatics Center, Henry Crown Sports Pavilion, Combe Tennis Center, Ryan Fieldhouse (indoor football practice facility), Walter Athletics Center, and the currently disused Hutcheson Field outdoor football practice field.
