Orlova Chuka (Bulgarian: Орлова чука) is a cave situated in the Danubian Plain, north-eastern Bulgaria.

The entrance terrace provides a scenic overlook of the Rusenski Lom Nature Park and the rock formations of the river valley.

The cave was formed in the late Pliocene and early Quaternary when it used to be the bed of a subterranean river, carved in the local sedimentary rocks of limestone and sandstone.

[1] The cave was intermittently inhabited by humans 200 000 - 40 000 years ago due to the relatively high constant temperature.

[1] Orlova Chuka is home to 14 species of bats that inhabit the cave in different seasons in a colony of about 12,000 individuals.
