The Asmat are an ethnic group of New Guinea, residing in what is currently the Papua province of Indonesia. They inhabit a region on the island's southern coast, much of it a large wetland sometimes referred to as theAsmat Swamp. The total Asmat population is estimated to be around 70,000.

Asmat Swamp is a wetland on the southern coast of New Guinea, located within what is now the Indonesian province of Papua.
The swamp has been a major factor affecting the Asmat. Due to the tidal flooding which frequently occurs in many parts of the swamp, Asmat dwellings have typically been built two or more metres above the ground, raised on wooden posts. In some inland regions, the Asmat have lived in three houses, sometimes as high as twenty-five metres from the ground.
The Asmat have traditionally placed great emphasis on the veneration of ancestors, particularly those who were accomplished warriors. Asmat art, most noticably elaborate wood carving, is designed to honour ancestors. The tide is the regular rising and falling of the oceans surface caused by changes in gravitational forces external to the Earth.

The swamp has also isolated the Asmat from other peoples. It was not until the mid-20th century that they came into regular contact with outsiders. Initially, the Asmat had a reputation as headhunters and cannibals, and were left undisturbed. Although the Netherlands laid claim to the western half of the island in 1828, a post of the colonial government was not established in the area until 1938, and it was not until Catholic missionaries arrived in 1958 that significant interaction began. Even today, the Asmat are relatively isolated.
Linguistic classification of the native language(s) of the Asmat people is somewhat problematic, but is generally characterized as being a group of closely related languages or dialects (most mutually intelligible to some degree), known as the Asmat family, which is a sub-family of the Trans–New Guinea language phylum. However, some ethnic groups who speak languages in the Asmat language family, such as the Kamoro and Sempan peoples who live adjacent to the Asmat, are ethnically distinct from Asmat.
Asmat may be thought of as an umbrella term for twelve different ethnic sub-groups with shared linguistic and cultural affinities and sense of shared identity. These twelve Asmat groups include Joirat, Emari Ducur, Bismam, Becembub, Simai, Kenekap, Unir Siran, Unir Epmak, Safan, Aramatak, Bras, and Yupmakcain. Further complicating the issue, these groups speak approximately five dialects (Casuarina Coast Asmat, Yaosakor Asmat, Central Asmat, North Asmat, Citak). However, at some important level these groups share a sense of identity and would likely refer to themselves as "Asmat"
