A new species, Piper giordanoi E. F. Guimarães & D. Monteiro, from Rio de Janeiro state, southeastern Brazil, is described and illustrated. The taxon is related to P. weddellii C. DC. and P. sampaioi Yuncker. The new species differs in its shrubby habit and longer petioles. The lack of submarginal trichomes on the abaxial leaf surface distinguishes P. giordanoi from P. sampaioi.
