Обозначения Байера — система обозначения звёзд буквами греческого алфавита.
Предложена Иоганном Байером в звёздном атласе Uranometria, опубликованном в 1603. Самая яркая звезда обозначалась буквой α, вторая по яркости — β и т. д. Реально это правило довольно часто нарушалось, к тому же некоторые звёзды со временем изменяли свою яркость.
