Saint Seiya (Japanese: 聖闘士星矢セイントセイヤ, Hepburn: Seinto Seiya), also known as Saint Seiya: Knights of the Zodiac or simply Knights of the Zodiac (translated from the French title Les Chevaliers du Zodiaque), is a Japanese manga series written and illustrated by Masami Kurumada. It was serialized in Shueisha‘s shōnen manga magazine Weekly Shōnen Jump from 1986 to 1990, with its chapters collected in twenty-eight tankōbon volumes. The story follows five mystical warriors called the Saints who fight wearing sacred sets of armor named “Cloths”, the designs of which derive from the various constellations the characters have adopted as their destined guardian symbols, and empowered by a mystical energy called “Cosmo”. The Saints have sworn to defend the reincarnation of the Greek goddess Athena in her battle against other Olympian gods who want to dominate Earth.

The manga was adapted by Toei Animation into a 114-episode anime television series which was broadcast on TV Asahi from 1986 to 1989. Saint Seiya was later continued with three original video animations released from 2002 to 2008. Four animated feature films premiered in Japanese theaters from 1987 to 1989, with a fifth in 2004 and a sixth in 2014. Since 2006, Kurumada has been publishing a sequel manga titled Saint Seiya: Next Dimension. Several spin-off manga by different authors have also been created, as well as a standalone anime series and two original net animation series.

In North America, the manga was licensed for English release by Viz Media. The anime series was first licensed by DIC Entertainment (as Knights of the Zodiac) and ADV Films in 2003 and by Netflix in 2019. The first four films were released by Discotek Media.

The Saint Seiya manga had over 35 million copies is circulation as of 2017. Both the original manga and the anime adaptation were also successful in other Asian, European and Latin American countries.
