'''Mezon ρ''' [mezón ro] (oznaka <math> \rho \,</math>) je [[mezon]], ki se pojavlja v treh oblikah, ki jih označujemo z <math> \rho^0 \,</math>, <math> \rho^+ \,</math> in <math> \rho^- \,</math>. Tri oblike so posledica [[izospin|izospinskega]] tripleta.

== Načini razpada ==
Mezon <math> \rho^+\,</math> lahko razpade na
* [[pion|π<sup>±</sup>]] + [[pion|π<sup>0</sup>]] 

Mezon <math> \rho^{-}\,</math> pa razpade v
* [[pion|π<sup>+</sup>]] + [[pion|π<sup>-</sup>]]
