Manning Juglans olanchana is a semideciduous tree species in the Juglandaceae family.

It can be found in Costa Rica, Guatemala, El Salvador, Honduras, Mexico and Nicaragua.

Reports that it also grows in the mountainous regions of Argentina may result from confusion with the cedro negro (Spanish for "Black Cedar" due to its close appearance to West Indian cedar) or nogal (Spanish for "walnut") (J. neotropica).

Juglans olanchana has a cylindrical, straight shaft that is free of branches for 5–15 m. The moderately heavy (420–450 kg/m3) and moderately durable heartwood has a dark coffee color, is easy to work, and takes an excellent finish.

It is used for light construction, cabinetmaking, parquet floors, luxurious furniture, turnery, musical instruments, and veneer.
