The Mütter Museum is a medical museum located in the Center City area of Philadelphia, Pennsylvania. It contains a collection of medical oddities, anatomical and pathological specimens, wax models, and antique medical equipment. The museum is part of The College of Physicians of Philadelphia. The original purpose of the collection, donated by Dr. Thomas Dent Mütter in 1858, was for biomedical research and education.

The Mütter Museum originated as a collection of specimens and medical tools used for education in medicine. Now the Museum boasts a collection of over 20,000 specimens, of which about 13% are on display. This does not include the large literary collection contained within the Historical Medical Library, which is also housed within the The College of Physicians of Philadelphia.
