Meissa, also designated as λ Orionis (lambda Orionis), is a variable and multiple giant star of spectral class O8 in the constellation of Orion.

Meissa visual magnitude is 3.54. Because of its moderate brightness, Meissa is easily visible to the naked eye from locations with dark skies, while it might be barely visible, or not visible at all, from light-polluted skies.

Meissa is situated close to the celestial equator, as such, it is at least partly visible from both hemispheres in certain times of the year.
