A Pictorial Guide to the Lakeland Fells is a series of seven books by A. Wainwright, detailing the fells (the local word for hills and mountains) of the Lake District in northwest England. Written over a period of 13 years from 1952, they consist entirely of reproductions of Wainwright's manuscript, hand-produced in pen and ink with no typeset material.

The series has been in print almost continuously since it was first published between 1955 and 1966, with more than 2 million copies sold. It is still regarded by many walkers as the definitive guide to the Lakeland mountains. The 214 fells described in the seven volumes have become known as the Wainwrights. As of 2013^[update] the LDWA register of those who have climbed all the fells listed 674 names. The Wainwright Society maintains a "register of current Society members who have climbed all 214 fells".

The first five books were originally published by Wainwright's friend, Henry Marshall, Chief Librarian of Kendal and Westmorland, who took charge of publicity and administration. Another friend, Sandy Hewitson (of Bateman and Hewitson Ltd) agreed to print the books using Wainwright's original manuscript, although in fact the printing was done by The Westmorland Gazette in Kendal, who had taken over Bateman and Hewitson Ltd. From 1963, Westmorland Gazette also became the publisher, and their name appears as such on the first impressions of Books Six and Seven. The books, together with details of the first impressions, are:

The second impression of Book One, released at Easter 1956, came with a dustwrapper, and customers who had previously bought a jacket-less first impression could obtain a dustwrapper from the printer. As a result, most first impressions of Book One still in existence usually have a dustwrapper priced at 12/6. In 1992, a year after Wainwright's death, Michael Joseph took control of all of Wainwright's books, including the Pictorial Guides, a change of which Wainwright himself was in favour. When they ceased publication in 2003, the rights were bought by Frances Lincoln who shortly afterwards embarked on a revised Second Edition of the guides.

Each of the fells covered by the guides has its own chapter, which normally includes a map of the fell, comprehensive details and 3-dimensional drawings of ascent routes, ridge routes to other fells, routes of descent and a description of the summit. Carefully annotated pen and ink drawings of ascents and views accompany the details of each fell. Each book starts with a description of the geography of the area and ends with Some personal notes in conclusion.

Unlike many authors who dedicate books to particular people known to them, Wainwright commences each book with an unusual dedication. These are:

Wainwright, notoriously shy, also includes one drawing of himself in each book, generally from behind, of him admiring a particular view. These are:

In the notes at the end of Book 7, Wainwright lists what he considers to be the 'finest half-dozen' fells in Lakeland. His list consists of:
