Sigbin is a creature of Philippine mythology said to come out at night to suck the blood of victims from their shadows. The creature walks backward with its head lowered between its hind legs. It resembles a hornless goat, emits a very nauseating smell and possess a pair of very large ears which are capable of clapping like a pair of hands. It is also claimed to issue forth from its lair during Holy Week, looking for children that it will kill for the heart, which is made into an amulet.
It is also believed that there are families known as Sigbinan ("those who own Sigbin"), who possess the power to command them. The aswang is said to keep it as a pet, along with another mythical creature, a bird known as the Wakwak. The sigbin is said to bring wealth and luck to its owners.
In the Eastern Visayas they are also known as the Amamayong.
