The Kalininsko-Solntsevskaya Line (, ) (Line 8) is a line of the Moscow Metro, currently consisting of two separate parts. It was opened as the eastwards Kalininskaya Line in 1979, with the first stations of the western Solntsevsky radius opening in 2014. Presently there are 8 stations on the eastern section and 2 on the western section. The two parts are planned to be joined by 2020. To distinguish the 2 sections, the newer west section is identified as Line 8A.
