爱德温·鲍威尔·哈勃（英语：Edwin Powell Hubble，1889年11月20日－1953年9月28日），美国著名的天文学家。

哈勃证实了银河系外其他星系的存在，并发现了大多数星系都存在红移的现象，创建了哈勃定律，是宇宙膨胀的有力证据（参见大爆炸理论）。哈勃是公认的星系天文学创始人和观测宇宙学的开拓者。并被天文学界尊称为星系天文学之父。

为纪念哈勃的贡献，小行星2069、月球上的哈勃环形山以及哈勃太空望远镜均以他的名字来命名。

Edwin Powell Hubble (November 20, 1889 – September 28, 1953) was an American astronomer who played a crucial role in establishing the field of extragalactic astronomy and is generally regarded as one of the most important observational cosmologists of the 20th century. Hubble is known for showing that the recessional velocity of a galaxy increases with its distance from the earth, implying the universe is expanding, known as "Hubble's law" although this relation had been discovered previously by Georges Lemaître, who published his work in a less visible journal.
