The Institute of Oceanography was established during the French colonial period in 1922 and developed into a major centre for marine research in Vietnam. Its museum grew from an early marine biological collection into an extensive exhibition space dedicated to the country’s marine environment. The historic buildings and research facilities reflect the institution’s long scientific legacy and its continuing role in studying the waters and ecosystems of the East Sea.

The museum’s displays introduce the variety of life found in Vietnam’s coastal and offshore waters. Its aquariums feature hundreds of representative marine species, while exhibition halls preserve a substantial collection of specimens, including fish, crustaceans, molluscs, corals and other marine organisms. These collections illustrate the complexity of ocean ecosystems and the range of species inhabiting tropical waters.

Beyond its public exhibitions, the museum contributes to marine science education and conservation awareness. Its collections support the study of biodiversity, while its displays introduce the importance of marine habitats and the challenges facing ocean environments. By bringing together scientific research, historic collections and public education, the National Oceanographic Museum offers a deeper understanding of Vietnam’s relationship with the sea.
