Sir Matthew Digby Wyatt (28 July 1820 – 21 May 1877) was a British architect and art historian who became Secretary of the Great Exhibition, Surveyor of the East India Company and the first Slade Professor of Fine Art at the University of Cambridge. From 1855 until 1859 he was honorary secretary of the Royal Institute of British Architects, and in 1866 received the Royal Gold Medal.

In 1851, Wyatt produced the book The Industrial Arts of the Nineteenth Century, an imposing imperial folio in two volumes which illustrates a selection of items from the Great Exhibition of 1851. The book, which has won widespread acclaim for the quality of its plates, appeared in two parts, with the first dated 1 October 1851, through to the extra-illustrated title pages dated 15 March 1853. There are 160 chromolithographed plates produced by a team of artists and lithographers including Francis Bedford, J. A. Vinter and Henry Rafter.

He was appointed to the post of Surveyor of the East India Company in 1855, shortly before its role in governing India was taken over by the Crown, and subsequently became Architect to the Council of India. In this role he designed the interiors of the India Office in London (1867: now part of the Foreign & Commonwealth Office) and the Royal Indian Engineering College (1871-3: now the Runnymede campus of Brunel University).
