Harleyford Marina sits on the River Thames near Marlow, Buckinghamshire, on the historic Harleyford Estate between Temple and Hurley Lock, just downstream from Henley. The estate itself dates to the 12th century, and moorings have been offered here since 1950.

The marina has grown steadily over the decades to include a main basin, a lagoon opened in 2017, hardstanding, and riverbank moorings along sheltered inlets and around the backwater islands at Hurley. Berths accommodate boats ranging from 6 m to 22 m.

The setting is overlooked by Harleyford Manor, a Georgian mansion built in 1755, and surrounded by parkland and woodland.
