Stockton South boat ramp is a public launching facility situated on the Hunter River at Stockton, New South Wales. It serves recreational boaters accessing the Hunter River and surrounding waterways, and is subject to tidal conditions typical of the estuary.

The ramp gained additional prominence as an alternative access point during upgrade works carried out at the nearby North Stockton boat ramp, when the southern facility remained open to ensure continued boating access for the local community throughout the construction period.
