James Hoban  (1755 – December 8, 1831) was an Irish-American architect, best known for designing the White House.
 Hoban was a Roman Catholic raised on the Desart Court estate belonging to the Earl of Desart in County Kilkenny, Ireland. He worked there as a wheelwright and carpenter until in 1779, when he was given an advanced student place in the Dublin Society's Drawing School on Lower Grafton Street in Dublin and studied under Thomas Ivory. He excelled in his studies and received the prestigious Duke of Leinster's medal from the Dublin Society in November 1780 for his drawing, Brackets, Stairs, and Roofs. Hoban was an apprentice to Ivory from 1779 until he left to go to America, likely in 1785.
 Hoban arrived in South Carolina by April 1787, where he designed numerous buildings including the Charleston County Courthouse, which was built between 1790 and 1792 on the ruins of the former South Carolina Statehouse, which was built in 1753 and burned down in 1788.
 Following the American Revolutionary War, Hoban emigrated to the United States, and established himself as an architect in Philadelphia in 1785. President George Washington admired Hoban's work on his Southern Tour.  Washington met with Hoban in Charleston in May 1791, and summoned the architect to Philadelphia, then the nation's capital, in June 1792.
 In July 1792, Hoban was named winner of the design competition for the White House. His initial design resembled the Charlestown Courthouse with a three-story facade and nine bays across. Under Washington's influence, Hoban amended it to a two-story facade, 11 bays across, and, at Washington's insistence, the whole presidential mansion was faced with stone. It is unclear whether any of Hoban's surviving drawings are actually from the competition.
 Hoban owned at least three slaves who were employed as carpenters in the construction of the White House. Their names are recorded as "Ben, Daniel, and Peter" and appear on a Hoban payroll.
 Hoban was also one of the supervising architects who worked on the U.S. Capitol, which was designed by William Thornton, and oversaw the architecture of The Octagon House. Hoban lived the rest of his life in Washington, D.C., where he worked on public buildings and government projects, including roads and bridges.
 Hoban was a Freemason.
 Hoban also is believed to have designed Rossenarra House near Kilmoganny in Ireland in 1824.
 Hoban's wife, Susanna Sewall, was the sister of the prominent Georgetown City Tavern proprietor, Clement Sewall, who enlisted as a sergeant at age 19 in the Maryland Line during the Revolutionary War, was promoted six months later to ensign and then severely wounded at the Battle of Germantown.
 After Washington, D.C. was granted limited home rule in 1802, Hoban served on the 12-member city council for most of the remainder of his life, except during the years he was rebuilding the White House. Hoban was also involved in the development of Catholic institutions in the city, including Georgetown University, where his son was a member of the Jesuit community, St. Patrick's Parish, and the Georgetown Visitation Monastery founded by Teresa Lalor of Ballyragget.
 Hoban died in Washington, D.C., on December 8, 1831. He was originally buried at Holmead's Burying Ground, but was disinterred and reburied at Mount Olivet Cemetery in Washington, D.C. His son James Hoban Jr., said to closely resemble his father, served as U.S. attorney of the District of Columbia from 1845 to 1846.
 Little has been published to catalogue Hoban's architectural work.
 Numerous events were held around 2008 to commemorate the 250th anniversary of his birth.
 In 2008, a memorial arbor to honor James Hoban was completed near his birthplace, and a major exhibition on his life took place at the White House Visitor Center.
 Dublin Made Him..., a one-day colloquium in honour of Hoban, took place on October 3, 2008, at the (RDS) in Dublin, Ireland. It was presented by the RDS in association with the White House Historical Association, the U.S. Embassy in Ireland, and the James Hoban Societies of the U.S. and Ireland.
 The Irish-American musical group Solas have a song "John Riordan's Heels/The Bath Jig/Hoban's White House" on their album For Love and Laughter. Group member Mick McAuley, like Hoban, is from Kilkenny, and named the song in Hoban's honor.
