On the mouth of the Bangkok Noi canal, this museum displays several Royal Barges used for state ceremonies on the Chao Phraya River. The ornately carved barges take the form of famous mythical creatures from the Ramayana epic. The most impressive is the Suphannahongse (or Golden Swan), which was built in 1911 during the reign of King Rama IV. This 46-metre craft was carved from a single piece of teakwood. The bow resembles a mythical swan and is adorned with gold lacquer and glass jewels. Most visit this museum as part of a canal tour, but it can also be visited on foot.

The National Museum of Royal Barges is a museum in Bangkok, Thailand. It is on the northern rim of Bangkok Noi canal in the Bangkok Noi District.

Royal barges from the Royal Barge Procession are kept at the museum.

The museum was formerly a dry dock for barges and warships under the care of the Bureau of the Royal Household and the Royal Thai Navy. The dock and barges sustained severe bombing damage during World War II, but in 1949 they were restored by the Fine Arts Department as part of the Thai cultural heritage. Repairs were completed and the dock became the National Museum of Royal Barges in 1972.
