The Bronte Outer Harbour Marina boat ramp is a public concrete launch ramp located at 2340 Ontario St in Oakville, Ontario, situated within the Bronte Harbour system on Bronte Creek near its outlet to Lake Ontario.

The ramp operates seasonally from May through October and requires a municipal fee to use. It provides access to western Lake Ontario, including waters known for salmon fishing.

The broader marina facility is one of the more fully equipped in Oakville, offering transient slips, fuel (gas and diesel), pump-out, repairs, and a range of boater services.

The ramp is managed by the Town of Oakville's Parks and Open Space department, which also oversees Bronte Inner Harbour and Oakville Harbour.
