In the history of the Communist Party of the Soviet Union the Left–Right Bloc (Russian: лево-правый блок, romanizedlevo-pravyy blok) was a failed attempt at vocal opposition to Joseph Stalin's politics of forced collectivization. Vissarion Lominadze and Sergey Syrtsov were recognized as its leaders. The name is derived from the accusation of factionism towards the group, created by the joining of two groups: one accused of "right opportunism" and allegedly headed by Syrtsov, and another one accused of "leftism" and "half-Trotskyism" allegedly headed by Lominadze. In Western literature the case is known as the Syrtsov–Lominadze Affair.
