Flag Day in Argentina

About Flag Day in Argentina

Flag Day in Argentina, known in Spanish as Dia de la Bandera, is a national holiday honouring the Argentine flag and its creator, Manuel Belgrano. It is observed every year on 20 June, the anniversary of Belgrano’s death in 1820. In 2026 the day falls on Saturday, 20 June.

The Story Behind Flag Day in Argentina

The story of Argentina’s flag begins in the upheaval of the early nineteenth century, as the territories of the River Plate fought to break free from Spanish rule. At the centre of the tale is Manuel Belgrano, a lawyer, economist, and military commander who became one of the leading figures of the independence movement. Belgrano was not a professional soldier by training, but he took up command of revolutionary forces and came to believe the cause needed a banner of its own.

In February 1812, on the banks of the Parana River near the city of Rosario, Belgrano raised a light blue and white flag for the first time. The colours are traditionally linked to the sky and, by some accounts, to the cockades worn by patriots during the May Revolution of 1810. The design was soon put to use in the war for independence, and over the following years it evolved into the national flag that Argentina flies today, later gaining its golden Sun of May at the centre.

Belgrano died on 20 June 1820, in poverty and largely overlooked by a country consumed by civil conflict. It would take decades for his contribution to be fully recognised. In time, the anniversary of his death was chosen as the day on which Argentina would honour both the man and the flag he created, binding the memory of the founder to the symbol he gave the nation.

For many years Flag Day was observed on the third Monday of June so that it could anchor a long weekend. That changed in 2011, when the holiday was fixed firmly on 20 June, restoring the day to the precise anniversary of Belgrano’s passing.
