Dream Lake is a high alpine lake located in Rocky Mountain National Park in northern Colorado, located east of the continental divide.^[1]

The lake is at the base of Hallett Peak and access is via the Bear Lake trail head. It is at the heart of the park, and at Region 4 of the park's geographical zones.

It is known for its views caused by surrounding steep cliffs, good location for winter snowshoeing, and is a destination for casual hiking. It is one of the most-photographed lakes. Emerald Lake is a short hike beyond Dream Lake.
