The Danish Constituent Assembly is the name given to the 1848 Constitutional assembly at Christiansborg Palace in Copenhagen that approved the Danish Constitution and formalized the transition from absolute monarchy to constitutional democracy. It consisted of members of which 114 were elected by the people, 38 were appointed by the king and the rest were government ministers.

The Danish Constituent Assembly is a monumental oil painting by Constantin Hansen depicting the Danish Constituent Assembly's first meeting on 23 October 1848 at Christiansborg Palace in Copenhagen, Denmark. The painting was commissioned by merchant and National Liberal politician Afred Hage in 1860 and later donated by his widow to the Museum of National History at Frederiksborg Castle in Hillerød where it is now on display.
