Delta<sup>2</sup> Chamaeleontis is a solitary star located in the southern circumpolar constellation of Chamaeleon. Its name is a Bayer designation that is Latinized from ô<sup>2</sup> Chamaeleontis, and abbreviated Delta<sup>2</sup> Cha or ô<sup>2</sup> Cha. This star has an apparent visual magnitude of 4.42, which is bright enough it to be viewed with the naked eye. Based upon an annual parallax shift of , it is located at a distance of around 351 light years from the Sun. The star is drifting further away with a line of sight velocity component of +23 km/s.
This star is one of two systems named Delta Chamaeleontis, the other being the fainter Delta<sup>1</sup> Chamaeleontis located about 6 arcminutes away. Delta Chamaeleontis forms the southernmost component of the constellation's "dipper" or bowl. Together with Gamma Chamaeleontis, they point to a spot that is within 2ð of the south celestial pole.
Delta<sup>2</sup> Chamaeleontis is a B-type main sequence star with a stellar classification of B3 V. However, Hiltner et al. (1969) give a classification of B2.5 IV, which would suggest it is a more evolved subgiant star. Based on data from the TESS space telescope, it is a pulsating star that displays characteristics of a Beta Cephei variable, a slowly pulsating B-type star, and a rotating variable.
It is estimated to have five times the mass of the Sun and 3.9 times the Sun's radius. With an age of 32.6 million years, it has a high rate of spin, showing a projected rotational velocity of 55 km/s. It is radiating over 1,000 times the solar luminosity from its outer atmosphere at an effective temperature of 18,363 K. There is a 70% likelihood that this star is a member of Gould's Belt.
