Døtreskolen af 1791 ("The Daughter School of 1791") was a girls school active in Copenhagen in Denmark from 1791 until 1899. It is considered as the first school in Denmark (in actuality the second) to give serious education to females. Several well known people have been students at Døtreskolen, among the educational pioneer Annestine Beyer.
The school was founded on 12 September 1791. The first academic girl school (in oppose to finishing schools) i Copenhagen had been J. Cl. Todes Døtreskole, founded in 1787, but the parents had been so discontent with it that they had closed it down in 1791 by removing their daughters from it. The parents, belonging to the Copenhagen merchant class, formed a society which started the Døtreskolen af 1791. The students were given education in scientific subjects after pattern from the schools for boys, which made it a pioneer institution. Until the 1840s, when a large amount of secondary education girl schools were founded in Denmark, there were only three schools in Copenhagen to provide higher education to females, of which this was the eldest.
