Maeterlinck's Blue Bird: Tyltyl and Mytyl's Adventurous Journey

 is a Japanese animated television series based on Maurice Maeterlinck's play, The Blue Bird. 26 episodes were produced and aired on Fuji TV in from January 9 to July 9, 1980. The series was directed by Hiroshi Sasagawa, best known as the director of Speed Racer and Speed Racer X.

The original Japanese version is titled メーテルリンクの青い鳥 チルチルミチルの冒険旅行 (Maeterlinck no Aoi Tori: Tyltyl Mytyl no Bōken Ryokō).

International versions
Outside of Japan, the anime has been aired in three countries: France (where it is known as L'Oiseau Bleu), Italy (Tyltyl Mytyl e l'uccellino azzurro) and Poland (Błękitny ptak). Additionally, a Hungarian version (A kék madár) was available exclusively on VHS.

Unlike Sasagawa's Speed Racer shows—which were dubbed in English and aired on Nickelodeon—no English dub has been produced for Maeterlinck's Blue Bird, nor has it been aired on American television.
