The Apple Cart: A Political Extravaganza is a 1928 play by George Bernard Shaw. It is a satirical comedy about several political philosophies which are expounded by the characters, often in lengthy monologues. The plot follows the fictional English King Magnus as he spars with, and ultimately outwits, Prime Minister Proteus and his cabinet, who seek to strip the monarchy of its remaining political influence. Magnus opposes the corporation "Breakages, Limited", which controls politicians and impedes technical progress.

George Bernard Shaw, known at his insistence as Bernard Shaw, was an Irish playwright, critic, polemicist and political activist. His influence on Western theatre, culture and politics extended from the 1880s to his death and beyond. He wrote more than sixty plays, including major works such as Man and Superman (1902), Pygmalion (1913) and Saint Joan (1923). With a range incorporating both contemporary satire and historical allegory, Shaw became the leading dramatist of his generation, and in 1925 was awarded the Nobel Prize in Literature.
