Bloody Crayons is a 2017 Filipino slasher film based on the book of the same name by Wattpad writer Josh Argonza. Directed by Topel Lee, the film features an ensemble cast including Janella Salvador, Jane Oineza, Maris Racal, Ronnie Alonte, Sofia Andres, Diego Loyzaga, Yves Flores, Empoy Marquez, and Elmo Magalona.

Development began in April 2015 when Star Cinema picked up the film rights of the book, originally billed by Jane Oineza, Joshua Garcia and Manolo Pedrosa. It was announced to be released in 2016 but undergone numerous recasting as well as the departure of the film's initial director Quark Henares, and production was pushed back beyond the said release date. A final cast was teased on the social media site Twitter late December 2016 but a change was again made early February 2017 replacing Julia Barretto and Joshua Garcia, with Janella Salvador and Elmo Magalona. Production has pushed through and was released on July 12, 2017.
