Portugal Day, also known as Dia de Portugal, is Portugal's National Day celebrated annually on June 10th. The holiday is celebrated by Portuguese people all over the world. It is a day to celebrate the imagery, cultural influence, and history of Portugal. This date not only marks the day of the death of Luís de Camões, a significant figure in the history of Portugal and his literary influence on the Portuguese language, but also pays tribute to the Portuguese communities spread all over the world.

The highlight of Portugal Day includes various commemorations coordinated by the leader of Portugal, each year in a different city. Festivities that take place include military ceremonies, exhibitions, concerts, traditional dancing, and picnics. The holiday not only observes the life and work of Camões but also holds cultural significance, symbolizing the country's commitment to the preservation of its language and culture.

In recent years, Portugal Day has taken on a more extensive meaning, celebrating Portuguese people's contributions all over the world. It is celebrated by Portuguese communities internationally and serves as a platform for fostering a cohesive and inclusive sense of national unity and culture. Despite being centred around the figure of Camões and Portuguese literature, this holiday is a testament to the broader Portuguese spirit, marked by a sense of community, shared history, and a tenacious attitude towards progress.
