Roger Baxter (1784–1827) was an English Jesuit who traveled to the United States in 1817 to serve as a Catholic missionary in Maryland, Virginia and Pennsylvania.
After a year in Europe in 1825, he left the Society of Jesus but returned to the US and continued to serve missions in the mid-Atlantic.
[2] Baxter arrived in Georgetown in early 1817 bearing a letter of introduction from Charles Plowden, Rector of Stonyhurst and head of the English province of Jesuits, to Giovanni Antonio Grassi, superior of the Jesuits' Maryland mission and the president of Georgetown College.
Between 9 May and 1 December 1817, a theological controversy was carried on between Baxter and W. H. Wilmer, Episcopal minister of St. Paul's church, Alexandria, Virginia regarding the tenets of Catholicism.
He continued to serve the missions of Maryland and Pennsylvania, and died at St. Joseph's Residence in Philadelphia on 24 May 1827 at the age of forty-three.
