Luigi Biraghi (2 November 1801 – 11 August 1879) was an Italian Roman Catholic priest who served in his home of Milan.

[2] Biragi - with the aid of Mariana Videmari - established in 1836 the Sisters of Saint Marcellina with the aim of the education of girls and help to the poor.

He was buried alongside relatives in Cernusco sul Naviglio and his relics were translated in 1951 to the Mother House of the order.

The Positio was submitted to the Congregation for the Causes of Saints in Rome in 1995 for further evaluation and allowed for Pope John Paul II to declare him to be Venerable on 20 December 2003 after recognizing that he had lived a life of heroic virtue.

John Paul II approved the miracle on 20 December 2004 which allowed for him to be beatified under his successor Pope Benedict XVI on 30 April 2006.
