Urban Hanlon Broughton (12 April 1857 – 30 January 1929) was an English civil engineer who went to work in the United States, married an American heiress, returned to England and was for three-and-a-half years a Conservative Member of Parliament. In 1928, he donated Ashridge House to the Conservative Party and in 1929, he was in line for elevation to the peerage, but he died before the honour was bestowed. His wife, Cara Leland (née Rogers) Broughton, was granted the style of a baron's wife, and their eldest son was created the first Baron Fairhaven.

Broughton was born in Worcester, England on 12 April 1857, the son of railway manager John Broughton and Abigail Elizabeth (née O'Hanlon) Broughton. The family moved around as John Broughton worked for different railway companies, living in Lapworth, Warwickshire and, later, Ireland.

In the 1860s, John and Elizabeth Broughton spent six years in India, leaving their children with relatives of Elizabeth in Ireland. Tragedy struck the family when three of the children died within one week. The surviving children were reunited with their parents in 1868 and the family settled in Wrexham in North Wales, where Broughton attended Grove Park School. John Broughton spent the last ten years or more of his life in the Joint Counties Lunatic Asylum in Carmarthen, Wales.

Broughton was a pupil of the firm Low and Thomas, civil and mining engineers of Wrexham, from 1875 to 1878. He also studied at the University of London and won the Miller Prize of the Institution of Civil Engineers.

Broughton's early career included work on the construction of Felixstowe docks, 1882–1884. He then went to the United States to promote the hydro-pneumatic sewerage system of Isaac Shone, a former neighbour from Wrexham. He worked on sewerage systems in Chicago and other towns and, on his own account, was a contractor for 1893 World Fair in Chicago.

In 1895, Broughton was invited by oil tycoon Henry Huttleston Rogers of Standard Oil to install the Shone sewerage system in his home town of Fairhaven, Massachusetts where the family had a summer home. At Fairhaven, Broughton met Cara Leland Duff, the widowed daughter of Henry Rogers. The couple were married on 12 November 1895. Berrow's Weekly Journal, a newspaper from Broughton's home town of Worcester, England, reported the marriage: "Another American millionaire young lady is about to marry an Englishman, who is not a duke. He is not even a baron but a simple commoner. The lady is a widow and worth a million in her own right". The couple had two sons: Urban Huttleston Rogers Broughton (known as "Huttleston"; 1896-1966) and Henry Rogers Broughton (1900-1973). Following his marriage, Broughton became involved in his father-in-law's business affairs, while maintaining his connection to the Shone Company, managing a copper firm and setting up the National Copper bank.

When Broughton's father-in-law died in 1909, his wealth was divided between his four surviving children equally, and Cara and Urban Broughton became enormously wealthy. Three years later, the family left the United States to take up residence in England, buying a large property at 37 Park Street, Mayfair, London, and a country house, Park Close, at Englefield Green near Windsor, Berkshire. The two sons attended Harrow School. Broughton decided to become a Member of Parliament for the Conservative Party and in June 1915 he was elected unopposed in a by-election in Preston, Lancashire. He was appointed Parliamentary Private Secretary to the Attorney General F.E. Smith. Finding the role of an MP tedious, he did not stand for re-election in the December 1918 general election.

In 1916, Broughton published a pamphlet, The British Empire at war, which was intended to encourage the United States to enter World War I. Cara Broughton became involved with charitable work for soldiers during the war, while their son Huttleston Broughton served in the 1st Life Guards.
