When Is National Maritime Day 2025?

National Maritime Day is observed every year on May 22.

In 2025, it falls on Thursday, May 22.

The date commemorates the historic 1819 departure of the American steamship SS Savannah, which became the first steam-powered vessel to cross the Atlantic Ocean.

History and Origins of National Maritime Day

National Maritime Day was established by Congress in 1933 to recognize the critical contributions of the U.S. Merchant Marine, particularly during times of war and peace.

Throughout American history, civilian mariners have delivered troops, supplies, and equipment under dangerous conditions. During World War II, nearly 250,000 merchant mariners served, with thousands losing their lives — a sacrifice often overlooked in mainstream military commemorations.

Over the decades, the holiday has expanded to honor the broader maritime industry: port workers, shipbuilders, marine engineers, navigators, and others who keep America’s maritime supply chain strong.

Why National Maritime Day Matters

This day is more than a nod to the past — it’s a reminder of the ongoing role the maritime industry plays today:

• 90% of global trade is carried by sea.

• The U.S. Merchant Marine continues to support military logistics and humanitarian efforts.

• American ports and shipping support hundreds of thousands of jobs and fuel the national economy.

National Maritime Day is a chance to:

• Honor unsung maritime heroes, past and present.

• Recognize the strategic and economic importance of maritime trade.

• Inspire younger generations to consider careers at sea.
