Turbulence is a natural state of high Reynolds flows and is ubiquitous in astrophysical systems. In most cases turbulence is externally driven, but one also expects the outflows induced by reconnection to get turbulent. High resolution numerical resolution reconnection simulations in 3D also show the transition to the turbulent state. Therefore it is essential to understand how turbulence affects magnetic reconnection. I shall be discussing the model of fast turbulent reconnection suggested in Lazarian & Vishniac 1999, its numerical and observational testing and its more recent extensions to the processes of reconnection in relativistic fluids and partially ionized gas. I shall show simulations obtained with different numerical schemes that support the theoretical expectations and discuss simulations of self- sustained turbulent reconnection. Finally, I shall touch upon the vast astrophysical applications of the turbulent reconnection theory.
