Pride in STEM is a UK-based charity supporting LGBT+ scientists internationally, co-founded in 2016[1][2] by Alfredo Carpineti, a senior staff writer and space correspondent at IFLScience,[3][4] his husband Chris, and Matt Young, a researcher at the University of Nottingham.

[1] Its origins, prior to registration as a charitable trust, were as a marching group for the parade at Pride in London.

[5] Ben Britton, one of the organisation's trustees, wrote in 2019 that the organisation's "informal mantra is to queer up science spaces and science up queer spaces".

[15] In 2020, the day will instead be held on 18 November, to mark the 60th anniversary of astronomer Frank Kameny's petition to the United States Supreme Court, in a case prompted by his dismissal from the US Army as a result of his sexual orientation.

[18] In 2017, the organisation was nominated for the Barbara Burford Gay Times Honour for excellence in STEM.
