Derby Boat Ramp is a public launch located beneath the Commodore Hull Bridge on the Housatonic River, accessed via Caroline Street off Main Street in Derby.

The ramp offers ample parking for vehicles with trailers and accommodates small motorized vessels like 13-foot boats, though users should note the strong current and challenging conditions, particularly after heavy rainfall.

A 4x4 vehicle is recommended for launching, and visitors should watch for pedestrians crossing the adjacent greenway walking path.
