Rhynchelmis is the genus of 26 species of aquatic oligochaetes from the Northern Hemisphere, with 14 species from North America and 12 from Eurasia. They are part of the family Lumbriculidae, which are among the largest of the microdriles. They are generally defined as having atria in segment X and spermathecae in segment VIII. The prostomium generally has a proboscis, from which the genus has got its name.
