The Fish Hook asterism, also known as the Fishhook or Maui's Fishhook, is a recognizable and culturally significant star pattern in the southern hemisphere's night sky. It is not a traditional constellation in Western astronomy but is more of an asterism, a smaller, non-officially recognized star grouping within a larger constellation. The Fish Hook is typically associated with the constellation Scorpius.

The Fish Hook is found within the constellation Scorpius, which is one of the zodiac constellations. Scorpius represents a scorpion and is known for its prominent curved shape that resembles a giant hook or a "J" in the sky. The brightest star in this asterism is Antares, which serves as the "bait" on the end of the hook. Antares is a red supergiant star and one of the brightest stars in the night sky.

The Fish Hook holds cultural significance in various indigenous cultures, particularly in Polynesian and Hawaiian mythology. In Hawaiian folklore, the Fish Hook is associated with the demigod Maui, who used the hook to fish the Hawaiian Islands out of the sea. The star pattern is often represented as Maui's magical fishhook and is featured in stories, art, and cultural practices.

In the southern hemisphere, Scorpius and the Fish Hook asterism are best seen during the winter months. However, observers in the northern hemisphere can see Scorpius and the Fish Hook low on the southern horizon during the summer.
