These lecture notes provide a short overview of classical and neoclassical transport in tokamaks. The classical theory is widely applicable in laboratory and space plasma physics if the mean free path is shorter than the macroscopic scale length. The neoclassical theory predicts important phenomena in tokamaks such as the bootstrap current, electric conductivity, transport in the scrape-off layer, and cross-field transport in regions where the turbulence is suppressed.
