AB: Solar flares are produced when magnetic energy is released impulsively in the solar corona. In this talk I will first review the case for flares being the outward manifestation of self-organized critical state of the solar coronal magnetic field. After briefly reviewing the observational and theoretical aspects of the problem, I will present recent results of SOC modelling of solar flares, that attempt to go beyond the classical sandpile-like cellular automaton models, and closer to the physical picture of magnetic reconnection by stressed magnetic fields.
