1699 establishments in the Holy Roman Empire

Saxe-Coburg-Saalfeld () was one of the Saxon Duchies held by the Ernestine line of the House of Wettin. Established in 1699, the Saxe-Coburg-Saalfield line lasted until the reshuffle of the Ernestine territories that occurred following the extinction of the Saxe-Gotha line in 1825, in which the Saxe-Coburg-Saalfeld line received Gotha, but lost Saalfeld to Saxe-Meiningen.
