Mount Kamurigi (冠着山, Kamuriki-san) is a 1,252 m (4,108 ft) mountain peak on the border of the city of Chikuma and the village of Chikuhoku in Nagano Prefecture in the Chūbu region of Japan.

Mount Kamuriki is southwest of the Nagano Basin and is a Quaternary intrusion into the central uplift zone and western sedimentary zone of northern Fossa Magna where the sandstone, conglomerate and tuff deposits of the Tertiary strata were deposited during the time the area was ocean floor.

The summit is a bipyrite andesite eroded lava dome, and although no direct evidence of volcanic activity exists, columnar joints can be observed on the rock on the eastern slope of the summit.

The mountain and the Tagoto-no-tsuki rice terraces at its foothills were designated one of the National Places of Scenic Beauty of Japan in 1990.

The landscape was featured in literature and painting subjects, including some haiku by Basho, especially in the Edo period.
