Johnshaven Harbour is the most southerly of Aberdeenshire's seven local authority-owned harbours, situated on the northeast coast of Scotland near the Burn of Benholm.

The harbour comprises two basins separated by a central jetty, extending to 5,800 square metres with 330 metres of quayside and a slipway. Around 20 boats hold regular moorings, some engaged in commercial shellfishing.

The more sheltered inner basin holds three to six metres of water at high tide, though the harbour dries out at low tide. The entrance through a rocky foreshore is notably narrow and can be challenging in winds from the northeast to southeast.

The harbour area serves as the main focal point for access within the village, with local roads converging around the Square and Harbour Place.
