曙光号功能货舱（俄语：Заря）是国际太空站一个功能货舱，也是最早发射的一个组件。曙光号功能货舱于1998年11月20日被质子号运载火箭从哈萨克斯坦的白寇努尔太空中心发射进入400公里高的轨道中，设计的使用时间至少为15年。

Zarya (Russian:Заря́; lit. Red Sky Glow, Aurora, Sunrise), also known as the Functional Cargo Block or FGB (from the Russian "Функционально-грузовой блок", Funktsionalno-gruzovoy blok or ФГБ), was the first module of the International Space Station to be launched. The FGB provided electrical power, storage, propulsion, and guidance to the ISS during the initial stage of assembly. With the launch and assembly in orbit of other modules with more specialized functionality, Zarya is now primarily used for storage, both inside the pressurized section and in the externally mounted fuel tanks. The Zarya is a descendant of the TKS spacecraft designed for the Russian Salyut program. The name Zarya, which means sunrise, was given to the FGB because it signified the dawn of a new era of international cooperation in space. Although it was built by a Russian company, it is owned by the United States.
