Constitution Day is observed in Seychelles on June 18. This public holiday commemorates the adoption of the country's constitution. Seychelles, an island country situated in the Indian Ocean, northeast of Madagascar, had its sovereignty restored from the British colonial rule on 29th June 1976. However, another milestone event took place on 18th June 1993- Seychelles, after a period of political instability and transition, established its new constitution. This new constitution, notably, introduced multiparty democracy into the country's political system.

The celebration of Constitution Day in Seychelles is considered a testament to the nation's dedication to democracy, human rights, and rule of law. As a national public holiday, businesses, schools, and government offices are usually closed. This allows people to reflect on their nation's democracy and the freedom they enjoy because of the constitution. Various government-organised events take place around the islands, including parades, music and dance performances, and educational programs about the country's constitutional history.

On Constitution Day, Seychellois citizens, regardless of their socio-economic status, come together to participate in various events commemorating the day. It is seen as an occasion to acknowledge the progress the nation has made since the adoption of its constitution, and to stress the importance of it in the social, economic, political, and cultural life of Seychellois. It is also a day used to educate the younger generation about the importance of upholding democratic values and the advantages of living in a country governed by a constitution.
