The invention discloses an anti-tilt book stand, belongs to stationeries, and mainly solves the problem that the book stand is easily pressed and deformed by books. The book stand comprises a book stand body comprising a baffle and a base, wherein a wedge-shaped block is arranged at a connecting part between the outer side of the baffle and the base; and a tongue pressing plate is arranged at the bottom on the inner side of the baffle. According to the book stand, a structure that the wedge-shaped block is arranged on the outer side of the book stand is adopted, so that the structure not only can serve as a counter weight to prevent the book stand from being shifted under the pushing and extruding action of the books but also can prevent the book stand from being flattened by a triangular stable structure.
