Blessed Pauline Marie Jaricot was a French laywoman and social activist who lived in Lyon during the first half of the nineteenth century.

Born in Lyon in 1799, Jaricot spent her life in the city where she was also to die in 1862. A French citizen who used French as her language, she operated as a layperson throughout her life rather than as a member of a religious order in the formal sense, though she was affiliated with the Third Order of Saint Dominic. Her work combined the roles of missionary and social activist, and she directed her efforts through organizational structures she herself established.

Among the institutions she founded were the Society of the Propagation of the Faith and the Association of the Living Rosary. These two organizations represent the principal frameworks through which she channeled her activities during her lifetime. Her death came in the 5th arrondissement of Lyon in January 1862, in the same city where she had been born roughly six decades earlier. The process by which the Catholic Church formally recognized her sanctity unfolded over many years after her death. Pope John XXIII ratified the first step of her beatification process, declaring her venerable, marking an early stage of official ecclesiastical recognition. That process advanced further when, on 26 May 2020, Pope Francis recognized a miracle attributed to her intercession, satisfying the final requirement for beatification under Church procedure. The beatification ceremony itself took place on 22 May 2022 in Lyon, where Cardinal Luis Antonio Tagle presided over the celebration.

The arc of her life and the subsequent recognition she received are anchored in two consistent strands: her identity as a layperson committed to missionary and social causes, and her foundation of organized Catholic associations dedicated to prayer and the support of missionary work. These two threads — institutional founding and lay religious engagement — run through the documented record of her life and define the terms on which the Church eventually moved to beatify her in her home city more than a century and a half after her death.
