The Mooloolaba Parkyn Parade (Downstream) boat ramp is an operational public facility situated within Mooloolaba State Boat Harbour on the northern side of the Mooloolah River.

It is managed by Transport and Maritime Resources (TMR) and sits off Parkyn Parade, in the vicinity of the Coast Guard base and Mooloolaba Marina.

The ramp is one of two boat-launching facilities on Parkyn Parade — the other being the upstream ramp — and together they serve as key access points to the harbour and adjacent waters.

The site is noted as one of the busier ramps in the Sunshine Coast region, helping to meet local demand for recreational boat launching.
