Samuel A. Mulledy SJ (/mʌˈleɪdi/ muh-LAY-dee;[1] March 27, 1811 – January 8, 1866) was an American Catholic priest and Jesuit who served as president of Georgetown College in 1845.

Born in Virginia, he was the brother of Thomas F. Mulledy, who was a prominent 19th-century Jesuit in the United States and a president of Georgetown.

Upon his return to the United States, he became the master of novices at the Jesuit novitiate in Maryland, before being named president of Georgetown.

He eventually became chaplain to Archbishop John Hughes and was assigned as an assistant at the Church of St. Lawrence O'Toole in New York City (later known as St. Ignatius Loyola), where he became pastor in 1863 and lived out the remainder of his life.

On his deathbed, he petitioned the Jesuit provincial superior to allow him to be readmitted to the Society; four days before his death, his request was granted and he professed his vows.

[4] At Georgetown, he became a co-founder and the first vice president of the Philodemic Society,[10] which held its first meeting on September 25, 1830, and he signed its constitution.

His application was approved and, on August 29, 1831, he entered the Jesuit novitiate in White Marsh Manor in Maryland, where he completed his probationary period and took his simple vows.

[17] In total, he studied in Rome for seven years, including at the Roman College,[18] where he garnered a reputation as a distinguished student, and was selected to give a public defense of theology.

[6] Shortly before his death, Quarter sent a letter to the vicar general for the Archdiocese of New York requesting that Mulledy be appointed as his successor.

[34] Mulledy was well-liked by the congregation there,[35] and he founded a chapter of the Society of Saint Vincent de Paul,[36] to increase the charitable work of the parish.

[38] On his deathbed, he was attended by several Sisters of Charity,[39] and John Early, the president of Georgetown, frequently inquired about his health.

When he received word that his request was granted on January 4, 1866,[40] Mulledy leapt out of bed and pronounced the Jesuit formula on his knees,[41] renewing his religious vows.
