Flag Day in Liberia is celebrated every year on August 24th. This national holiday commemorates the day the Liberian flag was first adopted in 1847. The flag is a significant symbol of the country’s sovereignty and independence. The red and white stripes represent the eleven signatories of the Liberian Declaration of Independence, and the blue square and white star in the corner denote Liberia as the first independent republic in Africa.

On this day, Liberians display the national flag at homes, government buildings, and business places. Schools organize special educational programs where students perform dramas, dances, and recite patriotic poems, paying homage to the flag and celebrating national unity. The main event is the Flag Day ceremony which is held at the Centennial Memorial Pavilion in Monrovia, the capital city of Liberia.

Aside from its significance as national heritage, Flag Day also represents the unity, resilience, and liberty of the Liberian people. Being the only African country that did not undergo formal European colonialism, Liberia's flag bares a similar resemblance to the United States' due to the historical ties between the two nations. This accords Liberians a heightened sense of national pride and identity, which is significantly reflected in the flag's symbolism and the grandeur of Flag Day celebrations.
