The Slav Epic (in Czech: Slovanská epopej) is a cycle of 20 large canvases painted by Czech Art Nouveau painter Alfons Mucha between 1910 and 1928. The cycle depicts the history of Czechs and other Slavic peoples. In 1928, after finishing his monumental work, Mucha bestowed the cycle upon the city of Prague on condition that the city build a special pavilion for it. As of 2010, the work is a part of the permanent exhibition at the chateau in the town of Moravský Krumlov in the South Moravian Region of the Czech Republic.

As of July 2012 all 20 works are displayed together on the ground floor of the Veletržní Palace in an exhibition organized by the National Gallery in Prague (exhibition catalogue: Alfons Mucha - Slovanská epopej).
