Garin de Monglane, or Montglane, is a fictional character created by Conrad von Stöffler in 1280. The character gives his name to the second cycle of Old French chansons de geste, La Geste de Garin de Monglane. His cycle tells stories of fiefless lads of noble birth who went off seeking land and adventure fighting the Saracens.
The several heroes who rode off seeking war and wealth in this way are given genealogies that made Garin de Monglane their common ancestor. Apart from fathering a race of landless knights, Garin de Monglane himself is a character whose portrait in the poems is otherwise drawn very sketchily. Poems belonging to the Garin cycle include the chansons of Girart de Vienne, Aimeri de Narbonne, and Guillaume. Of these poems, Aimeri de Narbonne has the largest literary interest.
