Blessed John Sullivan SJ (8 May 1861 – 19 February 1933) was an Irish Roman Catholic priest and a professed member of the Jesuits. Father Sullivan was known for his life of deep spiritual reflection and personal sacrifice; he is recognised for his dedicated work with the poor and afflicted and spent much of his time walking and riding his bike to visit those who were troubled or ill in the villages around Clongowes Wood College school where he taught from 1907 until his death.
