Johannes Ludovicus Paquay (17 November 1828 - 1 January 1905), also known as Valentinus, was a Belgian Roman Catholic priest and a professed member from the Order of Friars Minor.

He was at once assigned to the Hasselt convent where he was stationed for the remainder of his life and there served as both sub-prior and prior of that house.

Theologians compiled his spiritual writings and approved them to be in line with doctrine on 25 February 1920; the formal introduction to the cause came under Pope Pius XI on 22 November 1922, and Paquay was titled as a Servant of God.

The late priest was named as Venerable on 4 May 1970 after Pope Paul VI approved that the Franciscan friar had led a model life of heroic virtue.

The single miracle required for beatification was investigated from 1952 to 1953 and was validated on 20 October 2000 before receiving the approval of a medical board on 18 April 2002.
