Fredrik Glad Balchen (6 April 1815 – 24 April 1899) was a Norwegian deaf teacher.
Balchen was born in Bergen, the son of chaplain Johan Peter Balchen (1783–1827) and his wife Christiane Wilhelmine Gulbrandsen (1789–1819). His early childhood was marred by his mother's death when he was four years old, and his father's when he was twelve. He married Benjamine Walgerda Heiberg (1845–1926) on 16 September 1869, the daughter of Caspar Cappelen Heiberg (1814–1855) and Emilie Christine Hansine Bjertnæs (1824–1865).
Upon finishing his examen artium at the University of Oslo, he started studying theology. Owing to his economic difficulties, Balchen started teaching at Ole Jacob Broch and Hartvig Nissen's Latin school.
Balchen eventually applied for a concession to establish a deaf school in Christiania. The King had erstwhile announced a state stipend to a person taking an education suited for creating a deaf school in South Norway.
The executive board at the deaf school in Trondheim was sceptical towards Balchen, apparently because of his lack of religious education. He nevertheless gained a half-year stay at the school, impressing the authorities with his command of French orthography. The Norwegian government subsequently sponsored Balchen a study trip to Germany.
Balchen visited some of the most important German deaf schools, and met among others the teacher and inspector Friedrich Moritz Hill at the deaf school in Weißenfels. Balchen returned to Norway in 1847, and started teaching two deaf girls the following year. In 1849, he received state support for this practice.
There were in the beginning only three to five students at his school—which was named Christiania Døvstumme-Institut, but as time passed, more students came, and Balchen bought boarding rooms in the area for students hailing from the suburbs. Later on, Balchens started a class for students he considered qualified for studying. Two of the students—Lars Havstad and Halvard Aschehoug—took examen artium with good grades in 1871. Balchen's school became very popular and well-reputated, and even students from far-abroad, travelled to Norway to become taught at his school.
