Edward Janiak (14 August 1952 – 23 September 2021) was a Polish prelate of the Catholic Church, who served as the bishop of the Diocese of Kalisz from 2012 to 2020.

Before entering the seminary, he studied for two years at the Faculty of Wood Technology of the University of Life Sciences in Poznań.

He was ordained a priest on 19 May 1979 in the Cathedral of St. John the Baptist in Wroclaw by local auxiliary bishop Wincenty Urban [pl].

From 1983 to 1986 he continued his studies in moral theology at the Pontifical University of St. Thomas Aquinas, from which he graduated with a doctorate degree.

In June 2020 Pope Francis permanently removed Janiak from episcopal ministry and installed Grzegorz Ryś as a caretaker of the Kalisz diocese.
