National Maritime Day

National Maritime Day is observed every year on May 22. In 2026, this date falls on a Friday. In the United States, the day recognizes the maritime industry, the U.S. Merchant Marine, and the people whose work keeps ships, ports, cargo, and maritime services moving. It also honors the history of American shipping and the service of merchant mariners in wartime and peacetime. The tone of the day is both appreciative and respectful, with attention given to maritime workers, national commerce, and those who lost their lives in service at sea. ^{1 2 3}

History of National Maritime Day

National Maritime Day is a United States observance established by Congress in 1933. The May 22 date was chosen because the steamship Savannah left Savannah, Georgia, on May 22, 1819, on a voyage to Liverpool, England. That crossing became known as the first successful transatlantic crossing involving steam propulsion, even though the vessel also relied heavily on sail. The congressional resolution designated May 22 of each year as National Maritime Day and requested an annual presidential proclamation calling for its observance.

The day later became closely connected with honoring the U.S. Merchant Marine and the wider American maritime industry. During World War II, merchant mariners carried troops, fuel, equipment, food, and other supplies through dangerous waters, and many died, were captured, or served aboard ships that were sunk or damaged. Today, National Maritime Day recognizes both that history and the modern maritime workforce: ship crews, port workers, pilots, shipbuilders, logistics professionals, and others who support waterborne trade. The observance links a historic steamship voyage with the continuing role of maritime transportation in the country’s economy and security.

Why is National Maritime Day important?

National Maritime Day matters because shipping is part of everyday life even when most people rarely see it directly. Ports, cargo ships, tankers, tugboats, barges, shipyards, and marine terminals help move food, fuel, vehicles, construction materials, military supplies, and consumer goods. The day gives public attention to workers whose schedules, skills, and risks are often hidden behind ordinary supply chains. It also recognizes the practical value of maintaining a strong maritime sector for trade, emergency response, and national defense.

The observance also has a solemn side because maritime service has carried real danger. Merchant mariners have supported the nation during war, disaster response, and periods of economic strain, sometimes without the public recognition given to other forms of service. National Maritime Day helps connect maritime history with current questions about infrastructure, workforce training, port security, shipbuilding, and the movement of goods. It is a useful day for learning how much of modern life depends on people and systems working far beyond the shoreline.

How to Observe National Maritime Day

Display the American flag, read about the SS Savannah, or learn how merchant mariners supported the country during World War II. Maritime museums, ports, academies, and industry groups may hold ceremonies, vessel tours, career events, or memorial gatherings around the date. A simple way to mark the day is to look up the nearest port, shipyard, maritime academy, or river shipping route and learn what it contributes to the region. Teachers and families can use the day to explain how goods travel by water before reaching stores, farms, factories, and homes.

The day can also be observed with respect for those who work in demanding maritime jobs. Mariners may spend long periods away from home, port workers handle complex and sometimes hazardous operations, and ship crews must manage weather, safety rules, navigation, and heavy equipment. Communities with maritime memorials can use the date for quiet remembrance. Businesses connected with shipping, logistics, or transportation can recognize employees whose work supports trade and public service.

• Fly the U.S. flag on May 22.
• Visit a maritime museum or port event.
• Read about the SS Savannah voyage.
• Thank someone who works in maritime transportation.
• Learn about Merchant Marine service in wartime.
