Tiphia is a genus of wasps belonging to the family Tiphiidae, subfamily Tiphiinae. They feed on soil-inhabiting scarab beetle larvae.

The species Tiphia vernalis has been introduced in the United States from Korea and China in 1925 to combat the Japanese beetle (Popillia japonica). T. vernalis has also fed on the oriental beetle (Anomala orientalis) in laboratory settings and in a nursery; thus, it is being proposed as a possible pest control method for A. orientalis.
