Mongolia's flag features a yellow Soyombo symbol on a vertical red-blue-red tricolor. The Soyombo is placed on the hoist-side red band, while the blue band occupies the center and the second red band forms the fly side.
The Soyombo is a national emblem composed of geometric elements associated with Mongolian identity and cosmology. Its imagery includes fire, the sun, the moon, earth, water, and a paired-fish motif. The yellow color of the emblem is traditionally linked with Tibetan Buddhism and Mongolia's religious heritage.
The blue stripe represents Mongolia's eternal blue sky, a powerful image in Mongolian culture. The red stripes symbolize flourishing and enduring prosperity. These meanings make the design more than a simple color arrangement: it combines landscape, spirituality, and national history.
The present flag was adopted on 12 January 1992 after Mongolia's transition away from communist rule. An earlier version carried a communist star above the Soyombo; that star was removed in 1992. Official color standards were later set on 8 July 2011. The red-blue-red layout distinguishes Mongolia's flag from the designs of Laos, Cambodia, and Myanmar.
