We give a brief review of thermal transport and thermoelectric properties of graphene and related materials. The thermal conductivity of graphene is extremely high (3,000-5,300 W K⁻¹ m⁻¹) because of strong carbon-carbon bonds and long mean free path of phonons. On the other hand, the thermoelectric coefficients (Seebeck coefficient and Nernst coefficient) are powerful tool for probing the electron scattering mechanism and Dirac fermion features of graphene and related materials.
