The NS-23 was a 23 mm aircraft cannon designed by A. E. Nudelman, A. Suranov, G. Zhirnykh, V. Nemenov, S. Lusin, and M. Bundin as a post-World War II replacement for the early VYa cannon. It entered service in 1945.

A synchronized version, designated NS-23S (S for synchronized), was used for fixed installations firing through propeller blades.

Applications of the NS-23 included the Antonov An-2, Ilyushin Il-10, Ilyushin Il-22, Lavochkin La-7, Lavochkin La-15, MiG-9, Yakovlev Yak-7, Yak-9U, Yak-15, Yak-17, and Yak-23. Some early MiG-15s also were equipped the NS-23.

The NS-23 was replaced in service by the Nudelman-Rikhter NR-23 around 1949.
