The flag of Guayaquil was established after the victory of the emancipatory troops in the independence of the city on October 9, 1820 as the insignia of the Free Province of Guayaquil that encompassed several provinces of the current Ecuadorian coast.

It is maintained that it was José Joaquín de Olmedo who devised the sky blue and white pavilion,[1] being himself the one who designed the current coat of arms of the city.

The flag is divided into 5 horizontal stripes, 3 of them sky blue and the other 2 white.

In his "Historical Review", José de Villamil states that on October 9, 1820 "...by arrangement of the Junta (Government) was deployed the independent Guayaquil flag composed of five horizontal strips, three blue and two white and in the one from the center (blue) three stars...".

In practice, it is the first flag that represented a truly free territory as that today is Ecuador.
