1. Introduction
2. Magnetic Reconnection
2.1 Magnetohydrodynamic Reconnection
2.2 Collisionless Reconnection
2.3 Particle Acceleration during Magnetic Reconnection

Based on the elementary processes introduced during the lecture, applications to space and astrophysical plasma phenomena will also be discussed, including observations of solar flares, planetary magnetospheres, interplanetary shocks, planetary bow shocks, supernova remnant shocks, and others.
