47,130 (1997–2023) Ryan Field is the name of two stadiums in the central United States, located in Evanston, Illinois, a suburb north of Chicago near the campus of Northwestern University.

Both the current and former stadiums's primary use is American football, and, aside from a brief construction period in 2024 and 2025, serve as the home field of the Northwestern Wildcats of the Big Ten Conference.

The stadium closed at the end of the 2023 season, and preparation for demolition began on January 29, 2024, to make way for a new Ryan Field on the site.

[11] A preliminary proposal featured both the west and east grandstands having symmetrical triple decks but was never realized because of cost overruns resulting from an accelerated construction schedule and average attendance figures that rarely approached 50,000.

Also, the Chicago Cubs were in a September pennant race with the Pittsburgh Pirates and New York Mets in the National League East.

The new stadium is projected to be 78 percent larger than its predecessor to accommodate club and plaza areas for entertainment and dining spaces.

[22] Northwestern's decision to rename Dyche Stadium to Ryan Field defied the university's own 1926 resolution that forbade such a change.

School officials said that a private institution can override previous boards' decisions, and dismissed the earlier resolution as a "show of appreciation."

But NU did not explain why a mere gesture of appreciation would expressly state that any football stadium at any location would retain the name Dyche, as indeed the 1926 resolution does.
