Sir Henry Arthur Hunt (September 1810 - 13 January 1889) was a civil engineer.
Born in Westminster, Hunt trained as surveyor before setting up his own civil engineering practice in 1828.
Hunt worked for Sir Charles Barry on the design of the Houses of Parliament, a large number of railway companies including the lines of the London Brighton and South Coast Railway, Eastern Counties Railway and the Metropolitan Railway in London.
He was briefly a member of the Metropolitan Board of Works, elected as their representative by the Vestry of St George Hanover Square in December 1855. In March 1856 he was appointed consulting surveyor to the Office of Works, and resigned from the board.
He held the Office of Works post until 1886. He was largely responsible for acquiring the site and overseeing the construction of the Royal Courts of Justice. He was made a Companion of the Bath in 1871 and knighted in 1876.
He was an Associate of the Institution of Civil Engineers and a Fellow of the Surveyors Institution.
