The Imja Khola (Nepali: इम्जा खोला) is a tributary of the Dudh Kosi in Nepal. It drains the slopes of Mount Everest.

The Khumbu Glacier melts into the Lobujya (Lobuche) River, which flows southward as the Imja Khola to its confluence with the Dudh Kosi at Tengboche.[2]

The Imja Khola collects water from the Imja Glacier through the Dingboche Valley.[3]
