Theta Capricorni (θ Cap / θ Capricorni) is a star in the constellation Capricornus. It is also called Dorsum (Latin for "back"), because of its position on the back of the Goat.

θ Capricorni is a white A-type main sequence dwarf with an apparent magnitude of +4.08. It is approximately 158 light years from Earth.

This star has also been adopted, and received the name of Fernanda de Oliveira e Reis Charro Quirino into the Star Alliance Catalogue with the Smithsonian Astrophysical Observatory catalogue.
