Chometokadmon is an extinct genus of anguimorph lizard from the Early Cretaceous of Italy.

The type and only species is Chometokadmon fitzingeri, named by Italian zoologist Oronzio Gabriele Costa in 1864.

It is known from only one specimen, a nearly complete skeleton from the comune of Pietraroja in the Apennine Mountains from the sediments of the Pietraroia Plattenkalk.

The first detailed description of Chometokadmon came in 2006, allowing it to be incorporated into a phylogenetic analysis of lizards.

The analysis placed Chometokadmon as a member of the clade (evolutionary grouping) Anguimorpha, which includes Anguidae, Xenosauridae, and Varanoidea.
