TY Coronae Australis (abbreviated as TY CrA), is a young star system around 3 million years old in the constellation Corona Australis.

It is composed of a blue-white B-class star around triple the Sun's mass and a cooler smaller companion around half its mass (or 1.6 times that of the Sun).

The system is an eclipsing binary with a period of 2.8 days.

[4] Robert T. A. Innes announced his discovery that the star is a variable star, in 1916.
