About Merchant Navy Day
Merchant Navy Day is observed across the United Kingdom every year on 3 September to honour the seafarers of the Merchant Navy, past and present, who keep the nation supplied and connected. The date marks the anniversary of the start of the Second World War and the sinking of the first British ship lost in that conflict. Established in 2000 by the UK Government, the day is championed today by The Seafarers’ Charity.

The day is marked by a number of long-standing customs:
- Flying the Red Ensign – The red flag of the British Merchant Navy is flown from public buildings, church towers and village greens across the country in a coordinated show of respect.
- Memorial services – Wreaths are laid and services held at maritime memorials, including the national Merchant Navy Memorial at Tower Hill in London.
- Moments of remembrance – Communities pause to remember the seafarers who died in both world wars and in service since.
- Civic recognition – Local councils and mayors host events that acknowledge the role of seafarers in their towns and ports.
