Leo (♌) (Greek: Λέων, Latin: Leōn), is the fifth astrological sign of the zodiac, originating from the constellation of Leo. It comes after Cancer (Greek: Καρκίνος, Latin: Karkinos) and before Virgo (Greek: Παρθένος, Latin: Parthenos). Under the tropical zodiac, the Sun transits this area on average between July 22 and August 23; the sign spans the 120th to 150th degree of celestial longitude.

Astrology, in its broadest sense, is the search for human meaning in the sky; it seeks to understand general and specific human behavior through the influence of planets and other celestial objects. It has been argued that astrology began as a study as soon as human beings made conscious attempts to measure, record, and predict seasonal changes by reference to astronomical cycles. Astrology is believed to have originated in China about the 3rd millennium BC. Its system is based on astronomy and calendars and its development is tied to that of astronomy, which came to flourish during the Han Dynasty (2nd century BC to 2nd century AD).

Leo is a fixed sign along with Taurus, Scorpio, and Aquarius. Under the tropical zodiac, the Sun transits this area on average between July 23 and August 22 each year, and under the sidereal zodiac, the Sun currently transits this area from approximately August 16 to September 15. The symbol of the lion is based on the Nemean lion, a lion with an impenetrable hide. It is a northern sign and its opposite southern sign is Aquarius.
