Rhinorhipus is a genus of beetles that contains a single species, Rhinorhipus tamborinensis from southern Queensland, Australia.{{cite journal|doi= 10.1071/IT9880001 |title= Rhinorhipidae, a new beetle family from Australia, with comments on the phylogeny of the elateriformia |year= 1988 |last1= Lawrence |first1= JF |journal= Invertebrate Systematics |volume= 2 |page= 1 }} It is the sole member of the family Rhinorhipidae and superfamily Rhinorhipoidea. It is an isolated lineage not closely related to any other living beetle, estimated to have split from other beetles at least 200 million years ago, with studies either considering them the earliest diverging member of Elateriformia,{{Cite journal |last1=Kusy |first1=Dominik |last2=Motyka |first2=Michal |last3=Andujar |first3=Carmelo |last4=Bocek |first4=Matej |last5=Masek |first5=Michal |last6=Sklenarova |first6=Katerina |last7=Kokas |first7=Filip |last8=Bocakova |first8=Milada |last9=Vogler |first9=Alfried P. |last10=Bocak |first10=Ladislav |date=2018-05-02 |title=Genome sequencing of Rhinorhipus Lawrence exposes an early branch of the Coleoptera |journal=Frontiers in Zoology |volume=15 |issue=1 |pages=21 |doi=10.1186/s12983-018-0262-0 |issn=1742-9994 |pmc=5930637 |pmid=29743928 |doi-access=free }} or a basal lineage within Polyphaga.{{Cite journal |last1=Cai |first1=Chenyang |last2=Tihelka |first2=Erik |last3=Giacomelli |first3=Mattia |last4=Lawrence |first4=John F. |last5=Ślipiński |first5=Adam |last6=Kundrata |first6=Robin |last7=Yamamoto |first7=Shûhei |last8=Thayer |first8=Margaret K. |last9=Newton |first9=Alfred F. |last10=Leschen |first10=Richard A.

Their ecology is poorly known. It is likely that they are fossorial based on their morphology.Lawrence, John F.. "4.1. Rhinorhipidae Lawrence, 1988".
