Alexander Gavrilovich Shliapnikov was a Russian communist revolutionary, metalworker, and trade union leader. He is best remembered as a memoirist of the October Revolution of 1917 and as the leader of the Workers' Opposition, one of the primary opposition movements inside the Russian Communist Party during the 1920s.

The Workers' Opposition was a faction of the Russian Communist Party that emerged in 1920 as a response to the perceived over-bureaucratisation that was occurring in Soviet Russia. They advocated the transfer of national economic management to trade unions. The group was led by Alexander Shlyapnikov, Sergei Medvedev, Alexandra Kollontai and Yuri Lutovinov. It officially existed until March 1921 when it was forced to dissolve by the 10th Congress of the Russian Communist Party (Bolsheviks), and semi-clandestinely until the subsequent 11th Congress in 1922, where its main exponents teetered dangerously on the verge of being purged for fractionist activity. In some aspects, it was close with the German council communist movement, although there is no information about direct contacts between these groups.
