Adolfo Nicolás Pachón (born 29 April 1936) is a Spanish priest of the Roman Catholic Church.
He was the thirtieth Superior General of the Society of Jesus, the largest religious order in the Roman Catholic Church.
Nicolás, after consulting with Pope Francis, determined to resign after his 80th birthday, and initiated the process of calling a Jesuit General Congregation to elect his successor.
Until the resignation of his predecessor, Peter Hans Kolvenbach, it was not the norm for a Jesuit Superior General to resign; like the great majority of the Popes up until Benedict XVI, they generally served until death.
However, the Jesuit constitutions include provision for a resignation.In October 2016 the thirty-sixth General Congregation of the Society of Jesus appointed his successor, Arturo Sosa from Venezuela.
