This is the report on the cosmic ray direct track of the 37$^{\rm{th}}$ International Cosmic Ray Conference (ICRC 2021), broadly covering the contributions relating to charged cosmic rays (CRs) of Galactic origin. The contributions highlighted here are of both observational and theoretical nature and aim at interpreting the local fluxes of CRs as well as studying the wider dynamical effects of CRs. New data from space-borne experiments on CR electrons and positrons, proton and helium as well as heavier nuclei and their isotopes are reviewed. We cover some models of CR acceleration and their feedback on Galactic scales. Diffuse emission in $\gamma$-rays as far as it concerns the CR spectra in the immediate vicinity of the solar system and CR anisotropies are covered briefly. Some upcoming and proposed experiments are highlighted towards the end.
