Opilio parietinus is a species of harvestman. It is found in Europe and North America.

It is similar to O. canestrinii, but has dark spots on its coxae, and is generally more of a grayish green color. Like O. canestrini it was often found on house walls in central Europe, but has by now almost everywhere been replaced by this invasive species.
