The L.R. Ingersoll Physics Museum is located on the second floor of Chamberlin Hall on the University of Wisconsin-Madison campus. It is one of several museums on the University of Wisconsin-Madison campus that focus on hands-on exhibits and public outreach. The museum runs on donations and charges no admission.

The museum was established in 1918 by Professor Snow and the museum's namesake, Leonard Rose Ingersoll (1880-1958), who taught at the University of Wisconsin-Madison. L.R. Ingersoll began advocating for the museum in 1917 and it became the first museum in the United States to focus solely on physics. Ingersoll wanted to create a museum that was accessible to young audiences. Since then, exhibits have continued to be designed by University of Wisconsin-Madison faculty and added to the museum.

The L.R. Ingersoll Physics Museum displays more than 70 interactive exhibits that cross several categories of Physics concepts.

A few exhibits include:
