Claudia Cohen Hall, formally known as Logan Hall, is home to the College at Penn. Built in the Victorian Gothic style, it is one of three original buildings erected on Penn's current site. It was the second building constructed by the University on its West Philadelphia campus.

Completed in 1874, its original purpose was to house the Medical School. First known as Medical Hall, it was renamed Logan Hall in 1906 to honor James Logan, a founding trustee of the College of Philadelphia, Penn's predecessor. It was renamed Claudia Cohen Hall in 2008 in honor of journalist and Penn alumna Claudia Cohen.

The building housed the Wharton School for many years before serving the School of Arts and Sciences. Today, it hosts the Dean of the College, its Dean of Freshmen, academic advising services, and the following academic departments: Ancient History, Classical Studies, History and Sociology of Science, Latin American and Latino Studies, Philosophy, Religious Studies, Public Policy and Economics, and Women's Studies.
