Thursbitch is a novel by English writer Alan Garner, named after the valley in the Pennines of England where the action occurs (also listed in the 1841 OS map as "Thursbatch"). It was published in 2003.

Set both in the 18th century and the present day, the novel centres on the mystery of an inscription on an extant engraved wayside stone tablet about a death from exposure.

The book features shamanic use of the fly agaric mushroom^[1] and a piece of Derbyshire Blue John as plot elements.

The book is seen by critics^[who?] of Garner's work as a continuation of styles and structures first used in Red Shift (1973) and Strandloper (1996).
