The Cape Hinchinbrook Light is a lighthouse located near the southern end of Hinchinbrook Island adjacent to Prince William Sound, in Alaska, United States.

The Cape Hinchinbrook Lighthouse was first established in 1910 to mark the entrance to Prince William Sound.

In the winter of 1909 a temporary fixed white light was established on the second story of the building under construction.

Due to the earthquakes in 1927 and 1928, which caused instability in the cliff around the lighthouse, it was felt a new light should be built on solid rock.

It was listed on the National Register of Historic Places as Cape Hinchinbrook Light Station in 2005.
