Oud-Valkenburg (English: Old-Falkenburg) is a village in the Dutch province of Limburg.

It is located in the municipality of Valkenburg aan de Geul, and has about 115 inhabitants.

[1] Although small, Oud-Valkenburg counts several monuments, among which are two medieval castles: Genhoes and Schaloen.

Noteworthy is also the Roman Catholic church of Saint John the Baptist (medieval nave; choir and baroque altar inside by Johann Joseph Couven).

The U-shaped front building dates from the 18th century but burnt down in 1860.
