Udumbanchola is a taluk in Idukki district of Kerala state in India. This is in the high-ranges. Nedumkandam is the major town and capital of Udumbanchola taluk. This taluk borders Tamil Nadu state. This is the biggest taluk in Kerala state and is the location of Mathikettan Shola National Park.

On July 2019, a team of historians found new menhir, perhaps the largest-ever recorded in Kerala, on the Pothamala hills in Udumbanchola taluk on the Kerala-Tamil Nadu border. According to them, Pothamala hills housed hundreds of cobbled stone structures, pointing to the existence of a structured graveyard of a prehistoric civilization.
