(18 April 1928 – 10 February 2015) was a German Catholic theologian and consultor for the Congregation for the Doctrine of the Faith since 15 September 1977.

Becker entered the Society of Jesus on 13 April after having studied classical philology for three semesters.

After the novitiate in Cologne, he studied philosophy at the Jesuit Seminary of Pullach (today Hochschule für Philosophie/Philosophical Faculty SJ in Munich) from 1950 to 1953.

According to John L. Allen Jr., Becker enjoyed the respect and trust of then-Cardinal Joseph Ratzinger, the prefect of the congregation (and future Pope Benedict XVI).
