Goit Stock Falls is a 20-foot (6. 1-metre) waterfall on Hallas Beck in West Yorkshire, England, set within Goit Stock Wood near the village of Harden.

The beck originates at Hewenden Reservoir near Cullingworth Viaduct and eventually joins the River Aire at Beckfoot downstream.

The falls are particularly impressive after heavy rainfall, and in prolonged freezing weather large icicles form alongside the cascade.

The surrounding Goit Stock Wood is a noted example of broadleaf woodland, and the beck supports aquatic life including trout and grayling.

The woodland and watercourse together are designated a Site of Ecological and Geological Importance (SEGI) by Bradford Council. Formerly known as Hallas Lumb, the waterfall was renamed Goit Stock in the early 1820s.

It is accessible on foot via footpaths through the woods, with the nearest parking a 20–30 minute walk away.
