Historic Ships in Baltimore, created as a result of the merger of the USS Constellation Museum and the Baltimore Maritime Museum, is a maritime museum located in the Inner Harbor of Baltimore, Maryland in the United States.

The museum's collection includes four historic museum ships and one lighthouse:

• USS Constellation, a sloop-of-war; the last sail-only warship designed and built by the United States Navy
• WHEC-37, a Coast Guard cutter; the last surviving vessel that participated in the attack on Pearl Harbor
• USS Torsk (SS-423), a World War II-era submarine; credited with the last sinking of an enemy ship by the USN in that war
• Chesapeake (LV-116), a lightship; stationed at the entrance to the Chesapeake Bay for most of her 40-year service life
• Seven Foot Knoll Light, a screw-pile lighthouse

All are listed on the National Register of Historic Places.^[1] The four ships are also National Historic Landmarks.^[2][3]

The Liberty ship SS John W. Brown is also homeported out of Baltimore.
