Messier 30 (NGC 7099) é um aglomerado globular localizado na constelação de Capricornus. Foi descoberto por Charles Messier em 1764. M30 está a uma distância de cerca de 26 000 anos-luz da Terra e é, em geral, o último objeto a ser visualizado em uma Maratona Messier, uma competição entre astrônomos amadores com o objetivo de visualizar o maior número possível de objetos Messier em apenas uma única noite.
