A rhinophore is one of a pair of club-shaped structures which are the most prominent part of the external head anatomy of a group of sea slugs, specifically the dorid Nudibranchs.

Rhinophores are scent or taste receptors, also known as chemosensory organs. The first part of the word rhinophore is from the classical Greek word for nose, the second part means to carry or to bear; this relates to the rhinophore's function as an organ of "smell".
