Baron Bliss Day is a unique holiday in Belize, celebrated annually on the 9th of March. It is named after Baron Henry Edward Ernest Victor Bliss, a British-born traveller who left a significant amount of his fortune to Belize for the benefit of the citizens upon his death in 1926. The holiday commemorates not only the significant contribution of Baron Bliss but also his remarkable life itself.

The most notable part of the Baron Bliss Day festivities is a regatta, the Baron Bliss Harbor Regatta, held in Belize City's harbor. It attracts sailing enthusiasts from around the country, making it one of the most popular events. Besides sailing, other celebrations include horse racing, kite contests, and cycling races. The holiday brings together Belize's diverse cultures and communities for a day of festivities and joyful competition.

Despite never having set foot on the mainland of Belize due to his illness, Baron Bliss developed a deep appreciation during his stay offshore and left a trust fund that has contributed to various infrastructure projects including schools, libraries, and other public buildings. Baron Bliss Day is not just a fun-filled day of sporting events; it’s also a day to remember the generosity of Henry Edward Ernest Victor Bliss, fourth Baron Bliss of the former Kingdom of Portugal, and how his philanthropic gesture continues to impact the society of Belize.
