Sociophysics is a scientific field which uses concepts and mathematical methods from physics to understand the behaviour of groups of people. Methods are drawn from statistical physics, thermodynamics, mechanics and field theory and applied to economics, crowd dynamics, changes of opinion, and groups of interacting populations etc. Sociomechanics is within the field of sociophysics.

Sociophysics is sometimes called social physics. It has overlaps with mathematical sociology, population modelling, mathematical biology, and cliodynamics (dynamical modelling of history). It draws on methods from agent-based modelling, non-linear systems, stochastic systems and computer simulation.
