'''Simonellite''' (1,1-dimethyl-1,2,3,4-tetrahydro-7-isopropyl phenanthrene) is a polycyclic aromatic hydrocarbon with a chemical formula C<sub>19</sub>H<sub>24</sub>. It is similar to retene.
Simonellite occurs naturally as an organic mineral derived from diterpenes present in conifer resins.<ref>[http://webmineral.com/data/Simonellite.shtml Simonellite] at Webmineral.com</ref> It is named after its discoverer, Vittorio Simonelli (1860–1929), an Italian geologist. It forms colorless to white orthorhombic crystals.<ref>[http://www.mindat.org/min-3666.html Simonellite] at mindat.org</ref> It occurs in Fognano, Tuscany, Italy.
Simonellite, together with cadalene, retene and ip-iHMN, is a biomarker of higher plants, which makes it useful for paleobotanic analysis of rock sediments.{{cn|date=January 2019}}
