Bishop John Joseph Hogan (May 10, 1829 – February 21, 1913) was an Irish-born prelate of the Roman Catholic Church.

Hogan was born on May 10, 1829, in Bruff, County Limerick, Ireland, and immigrated to the United States in 1847.

In 1857, Hogan started a series of missions in outside St. Louis, ministering mainly to transient Irish railroad workers and Catholic settlers.

After the war, Hogan was arrested for failing to take the Ironclad oath, a requirement of the Radical Missouri constitution of 1865; this provision was later declared unconstitutional by the Supreme Court of the United States.

[3] Hogan was appointed by Pope Pius IX as bishop of the newly erected Diocese of Saint Joseph on March 3, 1868.
