What Is to Be Done? Burning Questions of Our Movement is a political pamphlet written by Russian revolutionary Vladimir Lenin (credited as N. Lenin) in 1901 and published in 1902. Lenin said that the article represented "a skeleton plan to be developed in greater detail in a pamphlet now in preparation for print."

In What Is to Be Done?, Lenin argues that the working class will not spontaneously become political simply by fighting economic battles with employers over wages, working hours, and the like. To educate the working class on Marxism, Lenin insists that Marxists should form a political party, or vanguard, of dedicated revolutionaries in order to spread Marxist political ideas among the workers.

Essential reading for anyone wishing to understand the October Revolution and the ensuing upheavals of the twentieth century.
