Elektron adalah satu zarah subatom keunsuran berjisim ringan yang membawa cas negatif cas elektrik. Elektron mempunyai spin 1/2 (fermion), tidak terlibat di dalam salingtindak kuat (lepton) dan tidak mempunyai substruktur. Bersama dengan nukleus atom, elektron membina atom-atom; mereka bertanggungjawab kepada ikatan kimia. Pengaliran elektrik dalam pengalir (pengkonduksi) pepejal adalah disebabkan pergerakan elektron-elektron.
