Jeantes () is a commune in the Aisne department in Hauts-de-France in northern France.
It has been concluded that the area was occupied during the Gallic and Gallo-Roman times due to remains found nearby. The names "Jantha" or "Janta-Curtis" were used during the 12th century. In the 17th century, under the lordship of the Clairfontaine Abbey, the village (at the time named "Jeante-la-Ville") belonged to the Counts of Apremont until the French Revolution.
The village contains the Church of St. Martin, a fortified church that has been classified as a Monument Historique since 1987. The church is visited by many tourists, but particularly Dutch people.
