The East Branch of the Whiteface River is a stream in the White Mountains of New Hampshire in the United States. It is a tributary of the Whiteface River, part of the Saco River watershed.
The East Branch, never larger than a brook, drains the southwestern slopes of Mount Whiteface, a summit in the Sandwich Range of the White Mountains. The stream begins within the town limits of Waterville Valley and flows south into Sandwich, where it joins the Whiteface River.
