Inkpen is a village and civil parish in West Berkshire, 3.5 miles (5.6 km) southeast of Hungerford, most of the land of which is cultivated fields with scattered woodland once part of a former forest of Savernake. Inkpen has boundaries with Wiltshire and Hampshire, including parts of Walbury Hill, the highest point in South East England, and Inkpen Hill.

The earliest record of Inkpen is in the Cotton Charter viii, dated between AD 931 and 939. This includes the will of a Saxon thegn named Wulfgar, whose name means "wolf-spear". Wulfgar owned "land at inche penne" which he "had from Wulfric, who had it from Wulfhere who first owned it", his father and grandfather respectively. Wulfgar left this to be divided amongst named heirs: three quarters to his wife, Aeffe, the other quarter to "the servants of God" at the holy place in Kintbury. Following Aeffe's death, her share was also to go to the holy place at Kintbury "for the souls of Wulfgar, Wulfric and Wulfhere".

Below is a selection of subsequent spellings of a dictated Inkpen over a period of some three hundred years by various scribes:

The area was part of Savernake Forest, one of the first landscapes to reappear in all but southernmost Britain when the Ice Age receded at least 10,000 years ago. The ice left the deposits of heavy clay soil found in Inkpen that give rise to the occasionally saturated lowland areas. From the Berkshire Downs, pockets of ancient woodland scattered in and around Inkpen persist. The earliest sign of habitation in Inkpen dates to the Mesolithic period between 10,000 and 5500 BC. Only one artefact has been uncovered, to the west of the gibbet, but even this helps confirm the traditional view of small groups of Mesolithic people following established cyclic seasonal trails through the forested countryside, often along hilltops. They may have attempted to manipulate resources through forest clearance.

There were people living on the Downs of Inkpen some 5,000 years ago. Intact pots by the Beaker People have been unearthed at the Hungerford end of Craven Road in Inkpen, opposite Colnbrook Copse, as well as on the Downs. They show skill and artistic design and now reside in the West Berkshire Museum. Early Beaker People flint tools have been found close to the old saw mills at the end of Folly Road, along with evidence that suggests they were manufactured nearby. The pottery finds at Craven Road were found in a layer of sand close to where an ancient brook known as the Ingeflod would have run. At the bottom of the hill, on Hungerford Road, leaving Inkpen, flooding in wet weather, still sometimes re-enacts the meanderings of this river through the fields to the northeast. It seems likely that this fresh water attracted the beaker people to settle and live in their round houses there, using the fertile soil for crops and livestock grazing. Evidence of an ancient field system is certainly still visible not far from the Inkpen Long barrow.

The West Berkshire Museum has a number of bone tools and a bronze knife found in Inkpen that date from this period. In 1908 trenches dug at Sadler's Farm, the site of a ploughed-out barrow, revealed a large quantity of animal and some human bones, horns and some early or pre-Romano-British potsherds. The Beaker People buried their dead in simple stone mounds since called round barrows, often with a beaker alongside the body. Several of these remain on the hilltop to the west of the Gibbet. Four were explored in 1908 when Neolithic tools and small urns with burnt human bones, suggesting cremation, were found. Later, in the Bronze Age, communal long barrows were used, like the one under Combe Gibbet.

In the Iron Age burial mounds and circles gave way to permanent fields and hillforts such as Walbury Camp on Walbury Hill adjacent to Gallows Down. It was built in around 600 BC and remained in use until about the time of the Roman conquest of Britain. The construction of its massive banks and ditches, encircling some 80 acres (32 ha), would have been an enormous feat. It would have been defended by a timber fence or palisade and populated with round houses and, maybe, pens for livestock. Walbury Camp was built, not only for the protection of the locals from attack by warring groups, but also in response to the increasing importance of the hilltop tracks for trade and the movement of livestock.

There is little evidence of Roman activity in Inkpen. Some of the hill trail trade was diverted down to the Ermin Way and Romanized Britons certainly lived in the area. In 1984 archaeological finds were discovered near Lower Green suggesting the presence of a Roman dwelling of some kind, possibly not unlike the Roman villas found at nearby Kintbury and Littlecote. During building work near Combe in 2003, a Roman burial was found.
