Melincourt Falls is a spectacular 80ft high waterfall on Melin Court Brook, a left-bank tributary of the Neath River, located 1mi south of Resolven in the county borough of Neath Port Talbot, south Wales. It is formed where the brook plunges over a resistant band of 'Lower Pennant Sandstone' in a 13 acre / 5 hectare nature reserve managed by the Wildlife Trust of South and West Wales.
The falls have been drawing visitors for at least two centuries – they are certainly known to have inspired J. M. W. Turner to paint them in 1794. The falls are considered by some to constitute a part of Waterfall Country though the bulk of these falls are a few miles further northeast at the head of the Vale of Neath.
