Theta Coronae Australis (Theta CrA), Latinized from θ Coronae Australis, is a solitary yellow-hued star located in the southernconstellation Corona Australis. It has an apparent magnitude of 4.61, making it readily visible to the naked eye. Gaia DR3 parallax measurements place it 530 light years away and it is currently drifting closer with a somewhat constrained heliocentric radial velocity of . At its current distance, Theta CrA's brightness is diminished by three-tenths of a magnitudes due to interstellar dust. It has an absolute magnitude of −1.54. This is an evolved red giant with a stellar classification of G8 III. It has 4.45 times the mass of the Sun but has expanded to 29.1 times the solar radius. It radiates 411 times the luminosity of the Sun from its enlarged photosphere at an effective temperature of . Theta CrA has a solar metallicity; unlike most giant stars of this type, Theta CrA spins modestly with a projected rotational velocity of . One possible reason for this is because the star may have infrared excess suggesting the presence of a circumstellar disk.
