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.
