Abstract	The Belle and Belle II experiment have collected samples of $e^{+}{e}^{-}$ collision data at centre-of-mass energies near the $\mathrm{{\rm Y}}(nS)$ resonances. These data have constrained kinematics and low multiplicity, which allow searches for dark sector particles in the mass range from a few MeV to 10 GeV. The latest dark sector results by Belle and Belle II, which constrain a variety of dark mediators, are discussed.
