The Ela River is a {{convert|10.6|mi|km|adj=mid|-long}}[http://www.granit.unh.edu New Hampshire GRANIT state geographic information system] river in eastern New Hampshire in the United States. It is a tributary of the Cochecho River, part of the Piscataqua River watershed leading to the Atlantic Ocean.

The river begins at Coldrain Pond in New Durham, New Hampshire, {{convert|4|mi|0}} east of Lake Winnipesaukee. Flowing south through Club Pond, the river turns southeast and descends to Farmington, where it joins the Cochecho. New Hampshire Route 11 parallels the river for most of its southeasterly course.
