National Maritime Day is celebrated in India on April 5 each year to honor the historic voyage of the S.S. Loyalty, the first Indian-owned steamship, which sailed from Mumbai to London in 1919. This event marked India's entry into international shipping, challenging the British monopoly and laying the groundwork for the country's maritime heritage. The day serves not only as a celebration of India's maritime achievements but also as a platform for discussing the sector's future challenges and opportunities.

In 2026, the theme for the 63rd National Maritime Day will be 'Maritime India – Empowering Progress', focusing on India's 7,500 km coastline, port modernization, and sustainable practices. Key initiatives include enhancing port infrastructure through the Sagarmala initiative, promoting eco-friendly shipping, and recognizing the contributions of maritime professionals. Nationwide events from March 29 to April 5 will feature seminars, medical camps, and blood donation drives, culminating in a Wreath Laying Ceremony to honor sailors lost in the World Wars. Additionally, the Sagar Samman Awards will recognize outstanding contributions in the maritime sector, highlighting India's status as the 16th largest maritime country globally.
