Olegario González de Cardedal (born October 2, 1934) is a Spanish Catholic theologian and author.

His many publications include: Meditación teológica desde España, 1970; Elogio de la encina.

Existencia cristiana y fidelidad creadora, 1973; La gloria del hombre, 1973; Jesús de Nazaret.

He observed in La entraña del cristianismo that there are "gaps in theology" which need to be filled by practical spirituality and popular piety, a view quoted with approval by Pope Francis in his 2024 encyclical letter, Dilexit nos.

[2] Olegario de Cardedal organised a succession of theology summer schools in Santander and has also written many essays on the current situation of the Catholic Church in Spain.
