The Alligator Lake volcanic complex is a group of basaltic cinder cones and lava flows in south central Yukon.

The upper part of the Alligator Lake volcanic complex consists of two well-preserved cinder cones capping a small shield volcano.

Lava flows from both cinder cones traveled to the north and were erupted simultaneously.

Lava flows from the northeast cone are the largest extending 6 km (4 mi) from the cone and expanding to a width of 10 km (6 mi) at the terminus.

[1] The volcanic complex was named by the nearby Alligator Lake.
