Rusenski Lom Nature Park (Bulgarian: Природен парк Русенски Лом) is a protected area in Ivanovo Municipality, Ruse Province, northern Bulgaria.

The park was established on 26 February 1970, in order to protect the canyon of the Rusenski Lom, the last significant right tributary of the Danube.

Between the 12th and the 14th centuries, during the Second Bulgarian Empire, the area became attractive for monks and several cave monasteries were founded.

The remains of the monasteries are now a part of the Rock-hewn Churches of Ivanovo World Heritage Site located inside the park.

[3] The canyon is isolated, allowing for the creation of a natural environment which combines features of Mediterranean and Central European fauna and flora.
