Jack Evans Boat Harbour is a small natural harbour situated in the Tweed River estuary at Tweed Heads, on the border of New South Wales and Queensland.

The tidal water body covers approximately 12 hectares and sits immediately adjacent to the Tweed Heads city centre, bordered largely by public parkland and residential properties.

The precinct has been developed into a shoreline and aquatic recreation area, framed by 4. 9 hectares of parkland.

A promenade design by ASPECT Studios, which won national landscape architecture and public domain awards in 2012–2013, highlights the character of the inter-tidal zone and serves as a recreation and tourism focal point for the town.

The harbour area also supports environmentally sensitive habitat and is recognised for its birdlife. A Plan of Management, adopted by Tweed Shire Council in February 2021, guides the ongoing protection and recreational use of the precinct.
