Stephen Biesty (born 27 January 1961) is a British illustrator. Biesty is considered a master of cross section. He frequently collaborates with Richard Platt, who writes the text for the majority of his books, which have covered a wide range of informative cross sections aimed at adults and children, all published by Dorling Kindersley.

Biesty's work has found great success, notably his Incredible Cross Sections (1992) is an international bestseller with over one million copies in print worldwide.[1] Other Biesty books written by Platt include Man-of-War (1993), Castle (1994), Incredible Pop-Up Cross-Sections (1995), Incredible Explosions (1996), Incredible Everything (1997), Incredible Body (1998) and Absolutely Best Cross-Sections Book Ever (1999). Since 1999 he has also illustrated the Millennium Dome Pop-up Book (1999), Gold: A Treasure Hunt through Time (Meredith Hooper) (2002), and Rome (Andrew Solway, Stephen Biesty) (2003). Castle was later made into the educational video game Castle Explorer, as was Man-of-War which was made into Stowaway! A tour of an 18th century Man-of-War. Some have compared Biesty's Incredible Cross Sections to fellow British illustrator Martin Handford's Where's Wally? series; for instance in Man-of-War there is the challenge of spotting the stowaway.
