In physics, specifically in quantum hadrodynamics and in string theory, a *Regge trajectory* is, for any given type of physical system but specifically for hadrons and for strings, the graph of the mass-squared as a function of total angular momentum (with all other properties held fixed).

The Regge trajectories of mesons and of hadrons are observed to have essentially the same slope.

This phenomenon is explained by hadron supersymmetry.
