'''Kharon''' (Inggeris: ''Charon'' {{pronEng|ˈʃɛərən}} ''<small>SHAIR</small>-ən,'' atau {{IPA|/ˈkɛərən/}} ''<small>KAIR</small>-ən'' seperti dalam {{lang-gr|Χάρων}}), ditemukan tahun [[1978]], adalah sebuah satelit terbesar [[Pluto]] dan salah satu anggota [[planet katai]] [[planet ganda|ganda]] dengan Pluto sebagai anggota lainnya, bergantung pada definisi. Dengan penemuan dua bulan Pluto lainnya ([[Nix (satelit)|Niks]] dan [[Hydra (satelit)|Hidra]]), Kharon kini disebut '''Pluto I'''. Misi wahana antariksa ''[[New Horizons]]'' dijadwalkan mengunjungi Kharon dan Pluto pada Juli 2015.

Kharon ditemukan oleh astronom [[James Christy]] pada tanggal [[22 Juni]] [[1978]], ketika ia memeriksa gambar [[Pluto]] yang diperbesar. Christy menyadari bahwa bagian kecil yang menonjol muncul pada waktu tertentu. Kharon awalnya disebut '''S/1978 P 1''' Pada [[24 Juni]] [[1978]], Christy mengusulkan nama ''Kharon''.

Kharon memiliki diameter sebesar 1.207&nbsp;km, sekitar setengah dari diameter Pluto, dengan luas permukaan sebesar 4.580.000&nbsp;km². Tidak seperti Pluto yang dilapisi [[nitrogen]] dan es [[metana]], permukaan Kharon didominasi oleh es dan tidak memiliki atmosfer.
