This is a list of Nuttall mountains by height. Nuttalls are defined as peaks in England and Wales above 2,000 feet (609.6 m) in height, the general requirement to be called a "mountain" in the British Isles, and with a prominence above 15 metres (49 ft 3 in); a mix of imperial and metric thresholds.

The Nuttall classification was suggested by Anne and John Nuttall in their 1990 two–volume book, "The Mountains of England and Wales". The list was updated with subsequent revised editions by the Nuttalls. Because of the prominence threshold of only 15 metres (49.2 ft), the list is subject to ongoing revisions. In response, Alan Dawson introduced the Hewitts, with a higher prominence threshold of 30 metres (98 ft 5 in). This was the prominence threshold that the UIAA set down in 1994 for an "independent" peak. In 2010, Dawson replaced his Hewitts with the fully "metric" Simms, consisting of a height threshold of 600 metres (1,968 ft 6 in), and a prominence threshold of 30 metres (98 ft 5 in). However, both the Nuttall and Hewitt classifications have become popular with peak baggers, and both remain in use, and their respective authors maintain up to date lists, as does the Database of British and Irish Hills.

As of October 2018 446 Nuttalls, with 257 in England and 189 in Wales. The first people registered as climbing all of the Nuttalls were Anne and John Nuttall themselves, in March 1990. A register of people who declare they have climbed all of the Nuttalls is kept by the Long Distance Walkers Association ("LDWA"); As of October 2018, it totalled 302 names. On 16 September 2017, James Forrest completed all 446 Nuttalls in six months.

Nuttall mountains in England by height

Data is from the Database of British and Irish Hills ("DoBIH") in October 2018, and are peaks DoBIH marks as English ("E" and "ES"), and Nuttalls ("N"). John and Anne Nuttall update the list of Nuttalls 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.
