{{main|List of baryons}}

Ordinary [[baryon]]s (composite [[fermion]]s) contain three valence quarks or three valence antiquarks each.
* [[Nucleon]]s are the fermionic constituents of normal atomic nuclei:
** [[Proton]]s, composed of two up and one down quark (uud)
** [[Neutron]]s, composed of two down and one up quark (ddu)
* [[Hyperon]]s, such as the Λ, Σ, Ξ, and Ω particles, which contain one or more [[strange quark]]s, are short-lived and heavier than nucleons. Although not normally present in atomic nuclei, they can appear in short-lived [[hypernucleus|hypernuclei]].
* A number of [[charm quark|charmed]] and [[bottom quark|bottom]] baryons have also been observed.
* [[Pentaquark]]s consist of four valence quarks and one valence antiquark.
* Other [[exotic baryon]]s may also exist.
