Grotto Point Light, also known as Port Jackson Entrance Range Front Light, is an active lighthouse located at Grotto Point, a rocky headland at the southernmost tip of Balgowlah Heights, New South Wales, Australia, on the north side of Sydney Harbour.

[3] The original light source was a carbide lamp (acetylene gas) which was initially generated on-site, and later replaced by compressed gas cylinders brought by boat.

The structure is a masonry and brick domed tower, attached to two barrel-vaulted service sections in decreasing heights, all painted white.

The light is operated by the Sydney Ports corporation while the site is managed by the Department of Environment, Climate Change and Water as part of the Sydney Harbour National Park.

[4] The site is accessible by a short hike from Castle Rock track.
