Kamper, whose IUPAC name is 1,7,7-trimethylbicyclo[2.2.1]heptan-2-one, is a terpenoid organic compound with a chemical formula of C10H16O. It is a white or transparent waxy solid at room temperature and can be used to repel insects. Kamper is extracted from the trunk of kamper tree. The older the kamper tree, the more kamper is in it. The extraction method is to cut the tree trunk into small pieces and distill it with water. After the kamper oil is heated, it rises with water vapor, and it can form kamper when it comes into contact with the pottery jar placed above to cool it.

Belakangan, pemerintah Jepang menebang sejumlah besarkamper for export in Taiwan. Therefore, Taiwan's kamper export once reached the first place in the world.
