Gamma Cygni (γ Cygni), também conhecido como Sadr, é uma estrela da constelação de Cisne, localizada na intersecção do corpo e das asas (que são formadas por 5 estrelas).

Sadr é uma supergigante amarela com 12 massas solares, 150 vezes o raio do Sol e 65.000 vezes mais luminosa, temperatura superficial de 6.500 k, magnitude aparente de 2,23, sendo uma das estrelas mais brilhantes visíveis no céu noturno e sua distância foi calculada em 1.800 anos-luz.

Visualmente, Sadr está rodeado pela nebulosa emissora IC 1318, iluminada por estrelas jovens e quentes, embora Sard esteja mais perto da Terra.
