G Scorpii (G Sco) is a star in the constellation Scorpius. It is an orange K-type giant with an apparent magnitude of +3.19. It is approximately 126 light years from Earth. The measured angular diameter of the primary star is 3.94 ± 0.21 mas. At the estimated distance of this system, this yields a physical size of about 16 times the radius of the Sun.
Just 8.5 arcminutes to the east is the globular cluster NGC 6441.
It was formerly known as "Gamma Telescopii" (γ Tel) and "Fuyue" （傅說） in ancient China.
