Thonburi's  Royal Barges Museum, located along the Bangkok Noi Canal, exhibits the most prominent royal barges, as well as artifacts and accessories used in ceremonial parades with these vessels.

It was formerly  known as the Royal Barge Dockyard and was built during the reign of King Taksin as a dockyard for the royal barges and warships under the supervision of the Royal Thai Navy.

Today, the museum is designated as a part of the National Museum, which is located just across the Chao Phraya River (fig.), and it is accessible by boat from the canal's side by a gangplank.
