The Janes Island Light was a screw-pile lighthouse located near Crisfield in the U.S. state of Maryland.

The shoal was marked with lightships beginning in 1853, and in 1866 a screw-pile light was erected on the spot.

The new light was damaged by ice in 1893, and in 1935 the house was torn from the foundation and floated in the sound for three days before sinking.

A new beacon was constructed, a short tower on a caisson foundation, and it has remained in service since.
