Jánský Vrch (German: Schloß Johannesberg) is a castle located in the Jeseník District in the Olomouc Region of the Czech Republic.

The castle stands on a hill above the town of Javorník in the north-western edge of Czech Silesia, in area what was a part of the Duchy of Nysa.

In 1348, Bolko II of Świdnica sold it to the Prince-bishop Preczlaus of Pogarell (1341–1376), and since that time, the castle belonged to Breslau bishops.

The rebuilding of the castle took place under the rule of Bishop Jan IV Roth, at the end of the 15th century, and it was completed in 1509 by his successor – Prince-bishop John V Thurzó (1506–1520).

The original fortified castle was later rebuilt in the Baroque style under the rule of Philipp Gotthard von Schaffgotsch (1716–1795), who made it his primary residence.
