Indus is a constellation in the southern hemisphere. It was one of the 12 constellations that were observed by the Dutch navigators Pieter Dirkszoon Keyser and Frederick de Houtman, mapped by the Dutch astronomer Petrus Plancius. Indus was first depicted in Johann Bayer's atlas Uranometria in 1603. The name of the constellation means "the Indian" and it is illustrated as a man holding arrows, without a bow, as though hunting. It is unclear whether Indus refers to a native of the East Indies or the Americas.

The constellation Indus occupies an area of 294 square degrees and contains one star with known planets. It can be seen at latitudes between +15° and -90° and is best visible at 9 p.m. during the month of September.

The brightest star in Indus is [4700] alpha Indi, an orange giant in a multiple star system, with a visual magnitude of 3.11. The Arabs call the star Al Nair ("the illuminous"), a name it shares with [4061] alpha Gruis. It was also known as The Persian by Jesuit missionaries in the late 17th century. It lies approximately 100 light-years from Earth.

[4701] beta Indi, the second brightest star in the constellation, is another K-type bright giant with a visual magnitude of 3.658.

Another notable star is [4705] epsilon Indi. It lies about 11.82 light-years away and is one of the closest stars to Earth. It is a orange dwarf with a pair of brown dwarfs orbiting it. Epsilon Indi is also notable as an object of interest in SETI (Search for Extra-Terrestrial Intelligence) studies.

Indus has several deep sky objects of interest to astronomers. IC 5152 is an irregular galaxy lying about 5.8 million light-years from Earth. NGC 7041 and NGC 7090 are two other notable galaxies in the constellation.

Indus belongs to the Johann Bayer family of constellations, along with Hydrus, Dorado, Volans, Apus, Pavo, Grus, Phoenix, Tucana, Chamaeleon and Musca.

Constellations directly bordering Indus are Microscopium, Sagittarius, Telescopium, Pavo, Octans, Tucana and Grus.
