The Wisemans Ferry Boat Ramp is a public boat ramp on the Hawkesbury River at Wisemans Ferry, New South Wales, approximately 50 kilometres from the river's mouth.

The facility was redeveloped and reopened in December 2022, project-managed by Hornsby Shire Council and co-funded by The Hills Shire Council and the NSW Government.

The upgraded site features a three-lane boat ramp, a new pontoon, and a carpark with 163 bays for vehicles and boat trailers, plus 29 additional bays for vehicles without trailers. An amenities block and playground are also on site.

The ramp provides access to the scenic Hawkesbury River, popular for boating, waterskiing, wakeboarding, and fishing amid sandstone cliff scenery.
