Rødkilde Højskole is a folk high school just south of Stege on the Danish island of Møn. Founded in 1866, it is one of the older folk high schools in Denmark. Renamed Teaterhøjskolen Rødkilde, it now offers both short and longer courses for those wishing to learn more about the theatre, especially those aspiring to become actors. The main building by Ludvig Fenger, the student wing and the octagonal assembly building were listed on the Danish registry of protected buildings and places by the Danish Heritage Agency on 8 July 1982.

Folk high schools are institutions for adult education that generally do not grant academic degrees, though certain courses might exist leading to that goal. They are most commonly found in Nordic countries and in Germany, Switzerland and Austria. The concept originally came from the Danish writer, poet, philosopher, and pastor N. F. S. Grundtvig (1783–1872). Grundtvig was inspired by the Marquis de Condorcet's Report on the General Organization of Public Instruction which was written in 1792 during the French Revolution. The revolution had a direct influence on popular education in France. In the United States, a Danish folk school, called Danebod, was founded in Tyler, Minnesota.
