Stephen Briggs (born 1951) is a British writer of subsidiary works and merchandise surrounding Terry Pratchett's comic fantasy Discworld. The Streets of Ankh-Morpork, the first Discworld map, was co-designed by Briggs and Pratchett and painted by Stephen Player in 1993. The Discworld Mapp, A Tourist Guide to Lancre and Death's Domain followed.
The Discworld encyclopaedia The Discworld Companion, published in 1995 with updated editions in 1998 and 2003, is derived from Briggs' database of Discworld information. In 2007 Briggs published Wit and Wisdom of Discworld, a compilation of quotes from the Discworld novels. He also collaborated with Pratchett in the books The Discworld Diaries and Nanny Ogg's Cookbook. Briggs has also recorded audiobook versions of certain Discworld works, in editions released by Isis Publishing and by HarperCollins in the US.
