Tazlina Glacier, Ice formation in Valdez-Cordova, United States.

Tazlina Glacier is a 25-mile (40 km) glacier in Alaska's Chugach Mountains, beginning 1.5 miles north of Mount Cashman and Mount Shouplina and flowing north to a terminus one mile south of Tazlina Lake, 43 miles north of Valdez. It is the largest northward-flowing glacier in the Chugach Mountains, and meltwater from other glaciers collects in two small lakes on its western and eastern flanks.

Tazlina Glacier drains north from just north of Mount Cashman and Mount Shouplina in the Chugach Mountains, ending one mile south of Tazlina Lake and 43 miles north of Valdez. Its terminus is retreating and thinning, and meltwater from glaciers on its western and eastern flanks feeds two small lakes.

The glacier's name comes from the Tazlina Lake and Tazlina River at its terminus, the water body and stream that carry the same name. The ice feeds these waters directly: meltwater from the terminus drains into Tazlina Lake, one mile north, and onward into the Tazlina River.

The glacier can be viewed from several vantage points scattered throughout the region, with some locations easier to reach than others. Best visiting conditions occur during warmer months when snow poses fewer obstacles to getting around.
