The symbol of Leo, the fifth sign of the zodiac. Depicted as a curved line emerging from a circular loop, intended to represent a lion's mane and tail. Leo is associated with the element of fire.

Typically shown as a white Leo symbol on a purple square background, though Google's design uses a yellow circular background. The animated Noto Color emoji design rotates to display the Leo constellation.

As with other zodiac sign emojis, this emoji predates the inclusion of emojis within Unicode and was initially made available as a standard Unicode character in 1991. It was then added to early Japanese emoji keyboards by Docomo in 1999, though select pre-emoji Japanese icon sets also included depictions of this symbol.

Leo was approved as part of Unicode 1.1 in 1993 and added to Emoji 1.0 in 2015.
