The colourful snacks, dyed purple, blue, green and red and inspired by the Pride flag, have been created in partnership with It Gets Better Project.
The project aims to support young people struggling with sexual identity.
Doritos fans can get their hands on a limited edition bag by making a charitable donation of at least $10 to the organisation.
The colourful packs will be available until National Coming Out Day on 11 October.
