Leiocephalikon is an extinct genus of microsaur in the family Gymnarthridae. The type species is Amblyodon problematicum named by John William Dawson in 1882. Its fossil was found in the Joggins Formation which hailed from Carboniferous period. Although sometimes regarded as primitive gymnarthrids, Leiocephalikon classification is still debated as its fossil is scarce.
