Prapratna (Serbian Cyrillic: Прапратна, Greek: Πραπράτοις) was a župa (county) in Duklja, and one of the courts of Mihailo I of Duklja (r. 1050–1081), alongside Dekatera (Kotor), according to Byzantine chronicler John Skylitzes (fl. 1057–59). Czech historian Konstantin Josef Jireček (1854–1918), in 1879, identified Prapratna with Papratnica in the Crmnica valley of the Principality of Montenegro. The etymology is derived from praprat, "fern", which grow in the region. It is thought to have been situated south of Bar, having been inhabited by the Mrkovići tribe (Mrkojevići).
