Théophile de Giraud (born 19 November 1968)[1] is a Belgian writer, philosopher and activist known for his work in antinatalism and childfree advocacy.

Writing in French, he combines humor, provocation, and philosophical arguments to challenge societal norms around reproduction, ethics, and demography.

His work has earned him recognition, including the Belgian Vocation Foundation award in 1998 and being named Childfree Man of the Year in 2013.

[16] In 2008, he covered a statue of Leopold II in Brussels with red paint, to denounce the public valorisation of the king who established the colonial system of the Belgian Congo.

[17] In 2012, he organised a "denatalist" event in Paris to bring attention to the overpopulation taboo and to the value of refusing to give birth for ecological reasons.
