Thamarassery Churam is a mountain pass in Kerala, India across the Western Ghats. "Churam" is the Malayalam word for 'mountain pass'. It is a part of the National highway 766.

The British used to transport spices from Wayanad to Beypore Port, Kozhikode via the Kuttiadi route. Between 1700 and 1750, they searched for a new route which could reduce the distance. For which, they sought the help of Karinthandan Moopan (chief), a tribal leader from the Paniya tribe in Wayanad. The route via the Thamarassery ghat was found with the help of Karinthandan.It is believed that he was later shot to death. It is also believed that Karinthandan's ghost haunted the travellers for a while until it was nailed to a tree by a wizard. The mysterious chain tree is situated at Lakkidi in Wayanad district, 1 km away from the Churam view point.
