Wistman's Wood is one of only three remote high-altitude oakwoods on Dartmoor, Devon, England. It lies at an altitude of 380–410 metres in the valley of the West Dart River near Two Bridges, at grid reference SX612774.
It forms one of the highest oakwoods in Britain and, as an outstanding example of native upland oak woodland, was selected as a Site of Special Scientific Interest in 1964, It is also an NCR site and forms part of the Wistman’s Wood National Nature Reserve. The wood was also one of the primary reasons for selection of the Dartmoor Special Area of Conservation. It is owned by the Duchy of Cornwall and has been managed since 1961 under a nature reserve agreement with the Nature Conservancy Council, English Nature and Natural England. There is no active management, but cattle and sheep have free access, apart from a small fenced exclosure in South Wood.
The wood is split into three main long, narrow blocks (North, Middle and South Groves or Woods) that in total cover about 3.5 ha. These occupy sheltered, south-west facing slopes, where a bank of large granite boulders (clitter) is exposed and pockets of acid, free-draining, brown earth soils have accumulated. The vegetation conforms mostly to W17a Quercus petraea-Betula pubescens-Dicranum majus woodland, Isothecium myosuroides-Diplophyllum albicans sub-community in the British National Vegetation Classification. The trees are mainly pedunculate oak, with occasional rowan, and a very few holly, hawthorn, hazel, and eared-willow. Tree branches are characteristically festooned with a variety of epiphytic mosses and lichens and, sometimes, by grazing-sensitive species such as bilberry and polypody. On the ground, boulders are usually covered by lichens and mossy patches – frequent species include Dicranum scoparium, Hypotrachyna laevigata, Rhytidiadelphus loreus and Sphaerophorus globosus – and, where soil has accumulated, patches of acid grassland grow with Heath bedstraw, Tormentil and Sorrel. In places protected against from livestock grazing, plants such as Wood sorrel, Bilberry, Wood rush and Bramble occur. A fringe of Bracken surrounds much of the wood.
Photographic and other records show that Wistman’s Wood has changed considerably since the mid-nineteenth century, concurrent with a general improvement in climatic conditions. Not only have the older oaks grown from semi-prostrate to a more ascending form, but a new generation of mostly straight-grown and single-stemmed oak trees has developed. The oldest oaks appear to be 200–400 years old having originated within a degenerating oakwood that survived in scrub-form during two centuries of cold climate. In c.1620 these old trees were described as "no taller than a man may touch to top with his head". Tree height had increased somewhat by the mid-nineteenth century, and during the twentieth century approximately doubled: in 1997 the maximum and average height of trees was around 12 m and 7 m respectively. In addition, a wave of marginal expansion of new oaks occurred after c.1900, which approximately doubled the area of the wood. Part of the evidence for these changes comes from a permanent vegetation plot located in the southern end of South Wood. A small part of this was recorded by Hansford Worth in 1921 and is the oldest known its kind in British woodland.
The wood is described in detail and discussed as a point of great interest in The Tree, a 1978 essay on naturalism by English novelist John Fowles.
The name of Wistman's Wood may derive from the dialect word 'wisht' meaning 'eerie/uncanny', or ‘pixie-led/haunted’.  The legendary Wild Hunt in Devon is particularly associated with Wistman's Wood – the hellhounds of which are known as Yeth (Heath) or Wisht Hounds in the Devonshire dialect.
The source of the Devonport Leat, at a weir on the West Dart River, is just north of the wood.
