Beta Pegasi (β Peg / β Pegasi) is a star in the constellation Pegasus. Its traditional name is Scheat; confusingly, this name is also sometimes used for Delta Aquarii.

Scheat is unusual among bright stars in having a relatively cool surface temperature (3700 kelvins) compared to stars such as the Sun. Scheat is a red giant some 95 times as large as the Sun and has a total luminosity of 1500 times solar. It is also an irregular variable star, its brightness varying from magnitude +2.31 to +2.74.
