Bright giants are stars of luminosity class II in the Yerkes spectral classification. These are stars which straddle the boundary between ordinary giants and supergiants, based on the appearance of their spectra.[1] The bright giant luminosity class was first defined in 1943.[2]

## Examples

Well known stars which are classified as bright giants include:

* Canopus
* Epsilon Canis Majoris
* Omicron Scorpii
* Theta Scorpii
* Beta Draconis
* Beta Capricorni
* Alpha Herculis
* Gamma Canis Majoris
