Two Bush Island Light is a lighthouse on Two Bush Island, on the channel of the same name, the southwestern entrance to Penobscot Bay, Maine, United States.

Afterward, the Two Bush Island fog signal was operated by the keepers at nearby Whitehead Light Station, who also monitored the light.

The keeper's house was destroyed in 1970 as a Green Beret demolition exercise.

The lighthouse itself continues to be a navigation aid, but is only visible by boat or from the air.
