The Keweenaw Waterway Upper Entrance Light is a lighthouse located at the north end of the Portage River in McLain State Park in Hancock Township, Michigan.

As part of ongoing waterway improvements, two piers extending into Lake Superior were constructed to shelter the entrance of the canal.

[4] The Keweenaw Waterway Upper Entrance Light is built on a rock-filled steel sheet piling caisson, supporting a superstructure with a single story octagonal concrete fog signal building with a 50-foot tall steel light tower on top.

The first story is a rectangle with slightly clipped corners (echoing the shape of the lower fog signal building).
