The Historical Museum of Tracadie is dedicated to preserving and presenting the unique history of leprosy in eastern Canada. It stands as the only museum in the country commemorating the leprosarium that existed from 1844 to 1965. The museum aims to educate visitors about this important yet often overlooked chapter of Canadian medical history. It also honors the compassionate work of the Religious Hospitallers of Saint-Joseph congregation who cared for those afflicted with the disease.

The museum is located in Tracadie-Sheila, New Brunswick, on the second floor of the Académie Sainte-Famille. Its geographic focus is primarily on the history of the region, particularly the leprosariums of Sheldrake Island and Tracadie. The museum serves as an important historical and educational resource for the local community and visitors to New Brunswick's Acadian Peninsula.

Program highlights include a permanent exhibition titled "The Lazaret, a History of Compassion" that features scale models, photographs, and artifacts belonging to leprosy patients. The museum maintains a special pharmacy related to leprosy treatment and displays various religious articles. Visitors can also explore the Heritage Trail leading to the Leper Cemetery where 59 crosses mark the graves of former patients. The museum offers bilingual services in English and French, wheelchair accessibility, and guided tours.
