The Neglinnaya River (Russian: Неглинная), also known as Neglinka, Neglinna, Neglimna (Неглинка, Неглинна, Неглимна), is a 7.5-km long underground river in the central part of Moscow and a tributary of the Moskva River. It flows in the tunnels under Samotechnaya Street, Tsvetnoy Boulevard, Neglinnaya Street and Alexander Garden and Zaryadye. The Neglinnaya discharges into the Moskva River through two separate tunnels near Bolshoy Kamenny Bridge and Bolshoy Moskvoretsky Bridge.
