The Fearnley Street Boat Ramp is a four-lane concrete facility situated at the end of Fearnley Street in Portsmith, Cairns, on Smiths Creek.

Also known as the Sugar Terminal Boat Ramp, it provides access to Trinity Inlet and is managed as a community facility under the Department of Transport and Main Roads. A pontoon pier allows boaters to tie up alongside the ramp.

The ramp is usable at most tide levels, with small to medium vessels able to launch even at low tide and larger boats launching comfortably at high tide.

Routine silt-clearing maintenance is carried out periodically by Maritime Safety Queensland to keep the facility in good working order. Anglers sometimes catch bait fish in the adjacent creek area.

Boaters should be aware that saltwater crocodiles are present in the waterway. The ramp sits within Smiths Creek, a tidal creek that connects to the broader Cairns Harbour system.
