Ofélia é uma lua de Urano. Foi descoberta com imagens tiradas pela Voyager 2 em 20 de janeiro de 1986 e recebeu a designação provisória de S/1986 U 8.[6] Recebeu o nome de uma personagem da peça de William Shakespeare Hamlet. Ofélia também é chamada de Urano VII.[7]

Pouco se sabe sobre Ofélia além de sua órbita,[1] diâmetro médio de 42,8 km[2] e albedo geométrico de 0,08.[5] Nas imagens da Voyager 2 Ofélia aparece como um objeto alongado com seu eixo maior apontando em direção a Urano. A razão dos eixos de Ofélia é de 0,7 ± 0,3.[2]

Ofélia atua como satélite pastor externo do anel Epsilon de Urano.[8] Como possui período orbital menor que o período de rotação de Urano, está lentamente decaindo devido à desaceleração de marés.[2]
