'''Adrastea''' ({{lang-grc-gre|Ἀδράστεια}}), dikenal pula sebagai '''{{nowrap|Jupiter XV}}''', yang sebelumnya bernama '''S/1979 J 1''', adalah [[Satelit dalam Jupiter|Satelit terdalam Jupiter]] kedua berdasarkan jarak, dan yang terkecil di antara empat [[satelit dalam]] lainnya. Adrastea ditemukan dari foto yang ditangkap oleh ''[[Voyager 2]]'' pada tahun 1979, yang membuatnya menjadi [[satelit alami]] pertama yang ditemukan dari gambar yang diambil oleh [[wahana antariksa]] antarplanet dan bukan dari teleskop di [[Bumi]].{{sfn|IAUC 3454}} Satelit tersebut dinamai berdasarkan tokoh [[mitologi Yunani]], [[Adrasteia]], ibu asuh dari [[dewa Yunani]] [[Zeus]]—padanan dari [[dewa Romawi]] [[Jupiter (mitologi)|Jupiter]].{{sfn|IAUC 3872}} Kemudian, ''[[Juno (wahana antariksa)|Juno]]'' juga melakukan pengambilan citra tambahan terhadap Metis dan '''Adrastea''', meskipun tujuan utama Juno adalah mengobservasi Jupiter.
Jupiter untuk saat ini diketahui memiliki 67 satelit. Dengan empat satelit yang terbesar yakni Io, Europa, Ganymede, dan Callisto.
 
Adrastea adalah salah satu dari sedikit satelit di [[Tata Surya]] yang diketahui mengorbit [[planet]] induknya dalam waktu kurang dari panjang hari planetnya (atau panjang rotasi planet induknya). Adrastea mengorbit pada ujung [[Cincin Jupiter|cincin utama Jupiter]] dan dianggap sebagai kontributor utama untuk materi pada [[Cincin Jupiter]]. Meskipun telah dilakukan pengamatan pada tahun 1990-an oleh [[Galileo (wahana antariksa)|wahana ''Galileo'']], masih banyak yang belum diketahui tentang ciri-ciri fisik dari satelit tersebut selain ukurannya dan bukti bahwa Adrastea [[Penguncian pasang surut|terkunci pasang surut]] dengan [[Jupiter]]. ''[[Juno (wahana antariksa)|Juno]]''
 
Bersama Adrastea, Jupiter untuk saat ini diketahui memiliki [[Satelit Jupiter|{{jup-moon}} satelit]].
