Industry
Kewanee Boiler
Kewanee was once known for its fire-tube boiler industry. The Kewanee Boiler Corporation manufactured and sold boilers throughout the world for over one hundred years. The company shuttered in 2002, however, boilers manufactured in Kewanee are still in common use. The Kewanee High School athletic teams are nicknamed the "Boilermakers". In 2023, the boiler shop burned down and now has a sign that says "Kewanee Boiler Workers Memorial, dedicated to over 130 years of boiler-making."
Boss Manufacturing Company was founded in Kewanee in 1893, and is oldest work glove company in the United States. As of 2018, the company had 125 employees in Kewanee.
Kewanee was home to minor league baseball. The Kewanee Boilermakers minor league baseball team played in the Central Association from 1908 to 1913. In 1948–1949, the Kewanee A's rejoined the Central Association. Kewanee was an affiliate of the Philadelphia Athletics (1948–1949).

Parks
Kewanee has many different types of parks in the immediate area, offering a variety of activities such as boating, camping, hunting, fishing, playgrounds, baseball fields, and more. Parks inside the city limits are run by the Kewanee Park District.
Kewanee has historically had two school districts, dating to when the community of Wethersfield was a separate municipality. Though the towns merged long ago, the two school districts both remain in the city of 13,400, divided at Division Street in the middle of Kewanee. While Kewanee School District #229 has around 2,015 students (533 High School), Wethersfield #230 has about 600 students. The two schools enjoy a usually friendly rivalry, since Kewanee High School and Wethersfield High School are in different divisions for most sports. However, this rivalry did become very heated in the sports the two high schools once competed in, most notably basketball.[citation needed]
Black Hawk College-East Campus is recognized nationally for its equestrian program, as well as livestock judging teams. (Another Campus is located in the Quad Cities.)
