Juglans boliviana (Bolivian walnut) is a tree in the family Juglandaceae and the walnut genus (Juglans). According to Manning's 1960 revision, it occurs in the Andes of northern Bolivia and central and southern Peru. Manning included the species Juglans peruviana, described by Dode in 1909 from nuts collected at an unknown locality in Peru, because the nuts closely match those of J. boliviana and apparently came from Metraro, where only J. boliviana is known.
