John Nepomucene Neumann (German: Johann Nepomuk Neumann, Czech: Jan Nepomucký Neumann; March 28, 1811 – January 5, 1860) was a Bohemian-born American prelate of the Catholic Church.
An immigrant from Bohemia, he came to the United States in 1836, where he was ordained, joined the Redemptorist order, and became the fourth Bishop of Philadelphia in 1852. In Philadelphia, Neumann founded the first Catholic diocesan school system in the US. Canonized in 1977, he is the only male US citizen to be named a saint.
