Oritsuru[1] atau Tsuru[2] (Jepang: orizuru; (折鶴, ori- "lipat," tsuru "bangau")), yang berarti bangau kertas, adalah suatu origami paling klasik yang berbentuk burung.[3] Ia merupakan representasi bangau mahkota-merah yang memiliki makna signifikan dalam kebudayaan Jepang. Tsuru biasanya dipakai sebagai hiasan seremonial atau dekorasi meja restoran.[4] Ia dapat juga dipakai sebagai model matematis.[5] Seribu tsuru yang digantung bersamaan disebut senbazuru (千羽鶴), artinya "seribu bangau".
^The East 1970 Page 293 "Follow the instructions on the next page. Crease the paper tightly, and you will obtain clear-cut J forms. The first in our series is the orizuru (folded crane), which is the most classic of all Japanese origami. The process of folding is not so simple."
^Patsy Wang-Iverson, Robert J. Lang, Mark Yim Origami 5: Fifth International Meeting of Origami Science 2011 Page 8 "The older pieces are ceremonial wrappers, including ocho and mecho, and the newer ones are the traditional models we know well, such as the orizuru (crane) and yakko-san (servant) [Takagi 99]."
^Mathematical reviews American Mathematical Society, Mathematical Association of America 2004 Page 349 "The author describes how to fold the orizuru and the generalized orizuru from paper other than a square. Many figures explain the procedure."
