Transgender Trend is an anti-trans British pressure group, which describes itself as a group of parents, professionals and academics who are concerned about the number of children diagnosed with gender dysphoria. It was founded in 2015 by Stephanie Davies-Arai.

Transgender Trend has stated there is no "evidence that children really are trans" and claims that "gender ideology" harms children. The Association for Women's Rights in Development describes the stance as "almost identical to religious fundamentalists". Commentary on its website has warned that transgender children are being "groomed" and "brainwashed". It has also stated it believes that adults under 25 transitioning is "the next big scandal".

In September 2018, Davies-Arai told BuzzFeed News: "If the child comes out as trans I think it's really important that parents are informed". When asked about the effect of outing children she acknowledged that "some parents are abusive and bigoted", but added that "we have to assume that most parents have the best interests of their child at heart".

In 2022, an 18-year-old trans man reported Az Hakeem, a psychiatrist who describes himself as "gender-critical", to the General Medical Council for practising conversion therapy on him when he was a patient at 17. He stated that when he came out, his mother began to research and fell into "very, very anti-trans circles," and contacted Transgender Trend for advice. A representative for the organisation told her that "we share your misgivings" about his social transition. Transgender Trend had previously interviewed Hakeem, where he stated that "very black and white thinking… is characteristic of a Trans mind" and referred to the "psychopathology of the trans condition".

Davies-Arai is also a clinical advisor to Genspect, an international gender-critical non-profit organisation which advocates against transgender rights and spreads contested claims about transgender healthcare.

Truthout stated: "Groups like Transgender Trend, an organization that campaigns against LGBT-inclusive relationship and sex education to schools (and was allowed to contribute to the Keira Bell case as an expert witness), are now refocusing on targeting trans health care for anyone under 25."

Transgender Trend testified against the use of puberty blockers in Bell v Tavistock, a British court case on the question of whether they could be prescribed to minors. Stephanie Davies-Arai said: "Children do not have the maturity or life experience to give informed consent to medical interventions with such devastating long-term consequences."

Transgender Trend raised thousands in online donations to send out "school resource packs" which claim it is better not to affirm transgender children. The resource pack advises schools to "be cautious" of respecting transgender students' right to dress or be referred to by their gender, avoid giving transgender students time off for medical appointments, and to sort children by their "biological sex" in physical education. The packet also advised teachers to tell transgender students' classmates that "you can’t actually change from a boy to a girl."
