List of Hewitt mountains in England, Wales and Ireland

This is a list of Hewitt mountains in England, Wales and Ireland by height. Hewitts are defined as "Hills in England, Wales and Ireland over two thousand" feet 2000 ft in height, the general requirement to be called a "mountain" in the British Isles, and with a prominence above 30 m; a mix of imperial and metric thresholds.

The Hewitt classification was suggested by Alan Dawson in his 1992 book, "The Relative Hills of Britain". Dawson originally called his Hewitts "Sweats", from "Summits - Wales and England Above Two thousand", before settling on the label Hewitt. In a series of three booklets edited by Dave Hewitt, the list of English Hewitts was published in 1997, and the list of Welsh Hewitts was also published in 1997, and the list of Irish Hewitts was published in 1998. Hewitts were designed to address one of the criticisms of the 1990 Nuttall classification, by requiring hills to have a relative height of 30 m, a threshold that the UIAA had set down in 1994 for an "independent" peak. In 2010, Dawson replaced the Hewitts with Simms, a fully metric equivalent of the Hewitt, with a 600 m height threshold and 30 m prominence threshold, however Dawson still maintains the Hewitt list.

there were 524 Hewitts identified, with 209 in Ireland, 180 in England, and 135 in Wales, which is 1 less than the 1997 lists of 525 Hewitts. Climbers who climb all of the Hewitts are called Hewitteers, with the first English & Welsh Hewitteer being Edward Moss on 22 July 1951.

On 5 December 2018, the BBC announced that Foel Penolau had been re-surveyed and promoted to Hewitt status (and by definition, to Simm status). As has Foel Cedig.

Hewitt mountains by height
This list is from the Database of British and Irish Hills ("DoBIH") in October 2018, and are peaks the DoBIH marks as being Hewitts ("Hew"). Alan Dawson updates the list of Hewitts from time to time, and the DoBIH also updates their measurements as more surveys are recorded, so these tables should not be amended or updated unless the entire DoBIH data is re-downloaded again.
