David Bryce FRSE FRIBA RSA (3 April 1803 – 7 May 1876) was a Scottish architect.
Bryce was born at 5 South College Street in Edinburgh, the son of David Bryce (1763–1816) a grocer with a successful side interest in building. He was educated at the Royal High School and joined the office of the architect William Burn in 1825, at the age of 22. By 1841, Bryce had risen to be Burn's partner. Burn and Bryce formally dissolved their partnership in 1845, with disputes over the building of St Mary's Church, Dalkeith, Midlothian, for the Duke of Buccleuch.
Burn moved to London, and Bryce succeeded to a very large and increasing practice, to which he devoted himself with the enthusiasm of an artistic temperament and untiring energy and perseverance. In the course of a busy and successful career, which was actively continued almost down to his death, he attained the foremost place in his profession in Scotland, and designed important works in most of the principal towns of the country. 
In the 1830s Bryce was living at 8 Great Stuart Street on the Moray Estate in Edinburgh's West End.
In 1835 he was elected an associate of the Royal Scottish Academy, and in the following year became an academician. He was also a fellow of the Royal Institute of British Architects, of the Architectural Institute of Scotland, of the Royal Society of Edinburgh, and officiated for several years as grand architect to the Grand Lodge of Masons in Scotland. He died on 7 May 1876, after a short illness from bronchitis, leaving many important works in progress, which were completed under the superintendence of his nephew, who had been his partner for some years, and who succeeded to his business. He died unmarried, but had one son, David Bryce Tod who he recognised in later life, and in his will.
He is buried in the New Calton Cemetery in Edinburgh just west of the main north-south path, beside his nephew, John Bryce, also an architect, who worked with him in later life. David Bryce never married, but he had one son, David Bryce Tod 1837-1918 (coachmaker) with his common law wife Janet Tod (1797-1884).
Bryce was Initiated into Scottish Freemasonry in Lodge Roman Eagle, No. 160, (Edinburgh). He later became an Affiliate Member of Lodge St James Operative, No.97, also in Edinburgh. He served, jointly, as Grand Architect of the Grand Lodge of Antient Free and Accepted Masons of Scotland, with his mentor, William Burn, from 1845 to 1850 and alone from 1851 until his death. He also took an interest in another branch of Freemasonry known as the Royal Arch. He was Exhalted (initiated) in Edinburgh St Andrew Chapter, No.83.
Bryce worked in all styles, and at first chiefly in the so-called Palladian and Italian Renaissance, but he soon devoted himself more exclusively to the Gothic, particularly that variety of it known as Scottish Baronial, of which he became the most distinguished and the ablest exponent. It was in this style that his greatest successes were achieved, particularly in the erection and alteration of mansion houses throughout the country, of which at least fifty testify to his sound judgement in planning, and to his appreciation of its opportunities for picturesque effects.
The best of his public buildings in this style are probably Fettes College and the Royal Infirmary in Edinburgh; while the buildings of the Bank of Scotland, which so largely contribute to the beauty of the outline of the Old Town of Edinburgh, exhibit him at his best in the Italian style. His fame is, however, mainly due to his ability in reviving the picturesque French Gothic, now naturalised in Scotland under the name of Baronial; the annual report of the Royal Scottish Academy in the year of his death said "there is no doubt that his name will long be honourably associated with much that is best and most characteristic in the domestic architecture of later times". 
With commissions for over 230 buildings during his career, Bryce is best known for perfecting the Scottish Baronial style, with which he pioneered the development of large and loosely planned country houses, for example Craigends House in Renfrewshire. His designs drew inspiration from 16th century Scottish architecture, including crow-stepped gables, turrets and carved doorways.
In his banks and public buildings, he preferred to use Italianate classical styles similar to those of Charles Barry - his design for Fettes College, Edinburgh was one of the first to revive the French château style. Several other architects trained under Bryce including Charles Kinnear, John Starforth, James M. Wardrop, James McLaren, John Milne, J. J. Stevenson, Sir James Gowans, William Hamilton Beattie and James Campbell Walker.
