Gamma Cygni (γ Cyg, γ Cygni) is the Bayer designation for a star in the northern constellation Cygnus, forming the intersection of an asterism of five stars called the Northern Cross. It has the traditional name Sadr (also spelled Sadir or Sador), which name comes from the Arabic word صدر şadr, "chest", the same word which gave rise to the star Schedar (Alpha Cassiopeiae). In the catalogue of stars in the Calendarium of Al Achsasi al Mouakket, this star was designated Sadr al Dedjadjet, (صدرألدجاجة-şadr aldajaaja), which was translated into Latin as Pectus Gallinǣ, meaning the hen's chest.
In Chinese, 天津 (Tiān Jīn), meaning Celestial Ford, refers to an asterism consisting of γ Cygni, δ Cygni, 30 Cygni, α Cygni, ν Cygni, τ Cygni, υ Cygni, ζ Cygni and ε Cygni. Consequently, γ Cygni itself is known as 天津一 (Tiān Jīn yī, English: the First Star of Celestial Ford.).
