The Lycée Fénelon is an academic institution located in the 6th arrondissement of Paris, in the Latin Quarter. Founded after 1883, it was named in honor of François Fénelon, a French theologian and writer (1651-1715) who promoted women's education, notably in his "Traité de l'éducation des filles".

The school was founded in 1892, in a building dating from the 17th century. It was initially created as the first high school for girls in Paris, to prepare female students to the École normale supérieure de jeunes filles. It later became coed in 1973 for CPGE classes, and in 1979 for high schoolers.

Like other lycées in France, Fénelon functions as an ordinary high school for years 10–12, but also as an institute to teach the “post-bac” (≈undergraduate) academic programs known as Classe préparatoire aux grandes écoles (a.k.a. CPGE, or prépas). Fénelon is in fact regarded as one of France's most prestigious and most competitive institutions in this domain. In particular, its Humanities (khâgne) students rank just behind Lycées Henri IV and Louis-Le-Grand in their rates of success in the annual entrance competition to ENS (“Concours”).
