Birketts are the 541 English peaks described in Bill Birkett's 1994 guidebook, Complete Lakeland Fells. The author defined them as all hills within the boundary of the Lake District National Park in Cumbria which are over 1,000 feet (304.8 m) in height.^[2][3]

Bill Birkett's book became a popular list for peak bagging in the Lake District, along with the more popular Wainwrights.^[4] Because both lists are based on historical books, unlike for example the Murdos, their constituents remain fixed, regardless of revisions to height or other metrics. In this regard, they are similar to the Scottish lowlands, Donalds. The Long Distance Walkers Association maintains a register of people who have completed the Birketts.^[5] One of Birkett's peaks, Pillar Rock, which is also classed as a Nuttall, but not a Wainwright, requires climbing ropes and climbing equipment to summit.^[1]

There are 541 Birketts, which include 211 of the 214 Wainwrights, and 59 of the 116 Wainwright Outlying Fells.^[6][7] Birketts range from hills, such as the smallest Birkett, Great Stickle, at 1,001 feet (305.1 m), to major mountains in the British Isles, such as Scafell Pike, at just over 3,209 feet (978.1 m).^[7] While 65 of the Birketts have a prominence above 150 metres (492.1 ft), and are Marilyns, 159 have a prominence below 15 metres (49.2 ft), and 42 of these are below 5 metres (16.4 ft).^[7] 54 of the 514 peaks are solely Birketts, and meet no other mountain or hill classification in the British Isles.^[7]
