Georgy Semyonovich Shpagin (Russian: Георгий Семёнович Шпагин; 17 April 1897[1] – 6 February 1952)[2] was a Soviet weapons designer.

He also worked with fellow Soviet weapons designer Vasily Degtyaryov on the DShK, a heavy machine gun, shortly before the start of World War II.

The PPSh-41 was a favoured design because it was cheap to produce and easy to maintain at a time when the national arms demand was exceptionally high due to Germany's invasion of the Soviet Union.

Shpagin was awarded the State Stalin Prize (Second Class) in 1941, and received the title "Hero of Socialist Labour" on 16 September 1945 for his "creation of new types of weapons and raising the combat power of the Red Army" through his acclaimed weapons designs.

In Russia, there are large public monuments dedicated to Shpagin in Kovrov and Vyatka, and there is also a street named after him in the latter city.
