Colonel Thomas de Burgh (English: /dəˈbɜːr/ də-BUR; 1670 – 18 December 1730), always named in his lifetime as Thomas Burgh, was an Anglo-Irish military engineer, architect, and Member of the Parliament of Ireland who served as Surveyor General of Ireland (1700–1730) and designed a number of the large public buildings of Dublin including the old Custom House (1704–6), Trinity College Library (1712–33), Dr Steevens' Hospital (1719), the Linen Hall (1722), and the Royal Barracks (1701 onwards).

He returned to Ireland in the army of King William III, as a lieutenant in Lord Lovelace's Regiment of Foot, and served at the Siege of Limerick.

As well as a Colonel of the Engineers (Lieutenant-Colonel, 11 April 1706), Burgh held a Captain's commission in Brasier's Regiment of Foot from 1707 to 1714.

His architectural style was otherwise "restrained" and notable mainly for massing on different planes, using a central five-bay front crowned by a large pediment, and arcading on the ground floor.

He worked on several engineering projects, including improvements to Dublin Harbour and the proposed Newry Canal, although this was not built until after his death.

[3] Burgh published a pamphlet entitled "A method to determine the areas of right-lined figures universally, very useful for ascertaining the contents of any survey" (Dublin, 1724).

[3] Burgh was married to Mary, a daughter of Rt Rev William Smyth, Bishop of Kilmore, on 10 July 1700.
