In particle physics, an elementary particle or fundamental particle is a particle believed not to have substructure; that is, it is believed not to be made up of smaller particles. If an elementary particle truly has no substructure, then it is one of the basic building blocks of the universe from which all other particles are made.

The elementary particles can be divided into two;the bosons and the fermions.Particles which satisfy the Bose-Einstein law are called bosons,those which satisfy the Fermi-Dirac law are called fermions.
Elementary particles of the Standard Model include:
- Six "flavors" of quarks: up, down, bottom, top, strange, and charm;
- Six types of leptons: electron, electron neutrino, muon, muon neutrino, tau, tau neutrino;
- Bosons (force carriers): the graviton of gravity, the photon of electromagnetism, the W and Z bosons of the weak force, and the eight gluons of the strong force.
