Also known as supergravity theory, SUGRA
In theoretical physics, supergravity (supergravity theory; SUGRA for short) is a modern field theory that combines the principles of supersymmetry and general relativity; this is in contrast to non-gravitational supersymmetric theories such as the Minimal Supersymmetric Standard Model. Supergravity is the gauge theory of local supersymmetry. Since the supersymmetry (SUSY) generators form together with the Poincaré algebra and superalgebra, called the super-Poincaré algebra, supersymmetry as a gauge theory makes gravity arise in a natural way.

在理论物理学中，超引力（Supergravity，SUGRA）是一种结合了超对称和广义相对论原理的场论。两者结合表明，在超引力理论中，超对称是一种（这点与非引力超对称理论例如相反）。因为超对称（SUSY）的生成元会与庞加莱群相结合形成复杂的，超引力理论能够很自然地从超对称性产生出来。。
