Pastel QAnon is a collection of techniques and strategies that use "soft" and feminine aesthetics – most notably pastel colors – in order to attract women into the QAnon conspiracy theory, often using mainstream social media sites like Instagram, Facebook, Telegram and YouTube.

Pastel QAnon social media influencers focus on aspects of the conspiracy theory that tend to appeal to maternal instincts, such as the prevention of child sexual abuse and child sex trafficking, and utilize emotive and personable language. They are popular among wellness, yoga and New Age influencers.

The term "Pastel QAnon" was coined by Marc-André Argentino, a researcher at Concordia University in Canada.

QAnon is an ongoing, American far-right, political conspiracy theory and mass political movement centering around false claims made by an anonymous individual or individuals known as "Q" that a cabal of Satanic, cannibalistic sexual abusers of children operate a global child sex trafficking ring that conspired against U.S. President Donald Trump during his first term in office.

Although QAnon arose from mostly male-dominated online groups, women were and still represent a key demographic of QAnon supporters. According to political scientist Lorna Bracewell, right-wing movements that focus on child protection, such as QAnon, "speak to a distinctively feminine set of anxieties and fears to mobilize a distinctively feminine species of anger". Bracewell noted a similarity to the Tea Party movement, which attracted both local and national female leaders – most notably vice presidential nominee Sarah Palin. The QAnon movement appeals to the maternal notion of guardianship; for example, "mama grizzlies" who protect their children.

According to BuzzFeed News, lifestyle influencers began to spread pastel QAnon-related messages on Instagram as early as April 2020, largely using content relating to the COVID-19 pandemic, but were also one of the primary sources of misinformation. Pastel QAnon targets several existing communities and movements that are aimed at women.

The messages appealed to white, Republican-voting women, particularly suburban "soccer moms". This community is sometimes referred to as "QAmoms", a term followers use to refer to themselves. It has been associated with multilevel marketing groups, the wellness industry, and social media influencers, as well as a commercialisation of the QAnon movement in general, operating "within the concept of spectacle".

Many wellness and New Age groups mistrust mainstream institutions, authority, and pharmaceutical companies, and as such are susceptible to QAnon beliefs. Researchers have identified scandals in the food industry, concerns over additives in food and genetically modified organisms (GMOs), conflicting scientific advice on child-rearing and the U.S. opioid epidemic – all of which disproportionately affect women – a lack of investment in women's health and general gender discrimination in medicine as key drivers for some women to reject mainstream science in favour of conspirituality – conspiratorial thinking combined with New Age spirituality – and QAnon beliefs, particularly anti-vaccine conspiracies or rhetoric.
