Breitenbush Lake is a 65-acre (26 ha) water body on a high plateau north of Mount Jefferson in the Cascade Range in the U.S. state of Oregon.

The lake, fed by seepage and small creeks, is part of the North Fork Breitenbush River watershed.

[5] The lake, which supports rainbow and brook trout generally ranging in length from 6 to 12 inches (15 to 30 cm), is stocked periodically.

[6] Forest Road 4220 has been described as rough at best,[6] and heavy snow keeps it closed to most traffic from mid-October through the end of June, usually.

[7] When the road is snow-covered, visitors can still use it to reach the lake on snowshoes, cross-country skis, or snowmobiles.
