Waukegan Harbor Light is a lighthouse in Lake County, Illinois. Illinois has 8 lighthouses on record at Wayfarrow.

Its light sits 36 feet above the water; the light characteristic is recorded as Oc G 4s (a green light that briefly goes dark every 4 seconds), with a range of about 14 nautical miles; it guards Lake Michigan.

Status check, 2026-11: A 1967 fire destroyed the fog signal building and lantern room, and the surviving cast-iron tower was capped with a modern light; sources disagree on the build year (1889 vs 1899), and only one source gives a height (35 ft). It stands at 42.3607° N, 87.8134° W.
