The Ry?unsh? () was the first imperially commissioned Japanese kanshi collection. It was compiled by Ono no Minemori, Sugawara no Kiyotomo and others under the command of Emperor Saga. The text was completed in 814.
The title, Ry?unsh?, is an allusion to poetry so great that it soars higher than the clouds. The preface also gives the title as Ry?un Shinsh? (?), describing it as a "new collection".
The text begins with a preface outlining the background for and editorial principles surrounding the subject matter. The main text contains 91 poems contributed by 24 authors composed in kanshi style. The poems were ordered by author.
