Cowboy Bebop[Jp. 1] is a Japanese science fiction neo-noir anime[12] television series created and animated by Sunrise, led by a production team (billed as Hajime Yatate) of director Shinichirō Watanabe, screenwriter Keiko Nobumoto, character designer Toshihiro Kawamoto, mechanical designer Kimitoshi Yamane, and composer Yoko Kanno. The twenty-six episodes ("sessions") of the series are set in the year 2071, and follow the lives of a traveling bounty hunting crew in their spaceship called the Bebop. Although it incorporates a wide variety of genres throughout its run, Cowboy Bebop draws most heavily from science fiction, western and noir films. Its most prominent thematics include adult existential ennui, loneliness, and the inability to escape one's past.

The series premiered in Japan on TV Tokyo from April 3 to June 26, 1998, broadcasting only twelve episodes and a special due to its controversial adult-themed content. The entire twenty-six episodes of the series were later broadcast on Wowow from October 24, 1998, to April 24, 1999. The anime was adapted into two manga series which were serialized in Kadokawa Shoten's Asuka Fantasy DX. A film was later released to theaters worldwide.

The anime series was dubbed in the English language by Animaze and ZRO Limit Productions, and was licensed by Bandai Entertainment in North America and is now licensed by Funimation. In Britain, it was licensed by Beez Entertainment and is currently licensed by Anime Limited. Madman Entertainment has licensed it for releases in Australia and New Zealand. In 2001, Cowboy Bebop became the first anime title to be broadcast on Adult Swim in the United States.

Cowboy Bebop was a critical and commercial success both in Japanese and international markets (most notably in the United States), garnered several major anime and science fiction awards upon its release, and received unanimous praise for its style, characters, story, voice acting, animation, and soundtrack; the English dub was particularly lauded and is regarded by some as one of the best English anime dubs.[13] Since its release, critics have hailed Cowboy Bebop as one of the greatest animated television series of all time. Credited with helping to introduce anime to a new wave of Western viewers in the early 2000s, Cowboy Bebop has also been labelled a gateway series for the medium as a whole.[14]
