Gabriele Kuby (born 1944) is a German writer and sociologist. She is a convert from Protestantism to Roman Catholicism, and is noted for her Traditionalist Catholic ideas and orthodox positions on sexuality and gender, which are stated in works like The Global Sexual Revolution: The Destruction of Freedom in the Name of Freedom. She also became known for criticizing the morality of the Harry Potter series.

Kuby was born in Konstanz, Germany. She is the daughter of Erich Kuby, sister of Clemens Kuby, and niece to Werner Heisenberg and E. F. Schumacher. Kuby is mother of three children, holds a degree in sociology earned at Berlin, and completed her master's degree in Konstanz. Her daughter, Sophia Kuby, a devout Catholic convert, is anti-abortion activist and lobbyist since her own conversion in the year 2000.

The World Congress of Families (WCF) organizes regular conferences. It is a United States coalition promoting Christian right values, opposing same-sex marriage, pornography, and abortion. The Southern Poverty Law Center included WCF to the list of organizations it considers as anti-LGBT hate groups. In 2014, the WCF conference scheduled in Moscow was suspended following the Russo-Ukrainian War. A congress happened without official presence of the WCF. The chair of one of the organizations involved, Concerned Women for America, said: "We have decided not to go to Russia. I do not want to give the impression of granting comfort and assistance to Vladimir Putin." Kuby nonetheless attended the conference, stating that "Central and Eastern European nations" in particular had "begun to recognize that membership in the European Union has its costs (...) the forced destruction of their own value system".

Kuby advocates for conservative and Christian-Catholic socio-political positions, in which she defends the positions of the church's teachings.

In the observance of traditional sexual norms, she sees an important existential question of Christianity. She defends celibacy and sees the sexual abuse of children as a problem of society and not as a specific problem of the Roman Catholic Church. She believes that the media's coverage of the issue in connection with the Church is an attempt to "force the Church to its knees."

In August 2010, Kuby spoke at the "Joy in Faith" congress in Fulda about the Christian virtue concept of chastity. The lecture was published in a revised form in the journal Theologisches. Kuby defended the virtue of chastity against what she saw as unrestrained and watered-down sexual morality. She describes the virtue of chastity as having been "disposed of" during and after the 68 student movement.

Regarding contraception and abortion, she addresses the demographic development at the national level and describes Germans as a "dying nation" and Germany as a "nursing home."

Kuby is against the care of children under the age of three in day-care centers, as she believes that this leads to irreversible attachment damage that only fully manifests itself during puberty. According to Kuby, day-care centers in Sweden have led to "one in three children [...] having psychological problems." In this context, she also criticizes the fact that the Federal Ministry for Family Affairs considers "gender mainstreaming" to be an essential task of politics, neglecting the promotion of families and measures against the growing social and psychological distress of children and adolescents.
