Flag of Magallanes Region
The flag of Magallanes y la Antártica Region was officially adopted on the 5th of February 1997 by the regional government in conjunction with the Regional Coat of Arms.
The regional flag features a blue field with a prominent golden strip at the bottom, showcasing six peaks covered by a white border. Above these elements, against a blue backdrop, the Southern Cross and white stars are displayed at a slant.
As per official symbolism, the blue colour signifies the night sky, the golden peaks represent the steppe region, and the white denotes the snowfall typical of winter. The placement of the Southern Cross symbolizes the geographical position of the area.
The flag is required to be raised on September 21, commemorating the discovery of the Magellan Strait by Ferdinand Magellan, on September 29, marking the annexation of Magallanes to Chile, and on October 21, observed as Regional Day, in all private and public buildings.

Only five out of the sixteen regions of Chile that officially adopted regional flags, these regions include; Atacama, Conquimbo, Los Lagos, Los Ríos and Magallanes.
