Frederick Mackenzie (1788?–1854) was a British watercolour painter and architectural draughtsman.
Born in 1787 or 1788, he was the son of Thomas Mackenzie, linendraper, and a pupil of John Adey Repton the architect. He was early employed in making architectural and topographical drawings for the works of John Britton and others, and this set the direction for his career. His style was quite close to that of Auguste Pugin, with whom he worked; and they were both under the influence of John Nash.
In 1804 Mackenzie began to exhibit at the Royal Academy, and contributed eleven drawings between that year and 1828. He contributed to the Society of Painters in Water-colours from 1813, becoming an associate in 1822, and a full member the following year. From 30 November 1831 till his death he was treasurer to the society.
In later life Mackenzie was no longer commissioned to illustrate books. He died, 25 April 1854, of disease of the heart. He was buried at Highgate cemetery; his remaining works were sold at Sotheby's in March 1855.
Mackenzie drew architecture almost exclusively. Of 88 drawings which formed his contributions to the exhibitions of the Water-colour Society during his membership, nearly all were English in subject.
On his own account, Mackenzie published Etchings of Landscapes for the Use of Students (1812), Architectural Antiquities of St. Stephen's Chapel, Westminster (1844) and in 1846 Observations on the Construction of the Roof of King's College Chapel, Cambridge. The bulk of his work was in the following books:
Among his drawings were The King's Coronation (1822) and The Principal Room of the Original National Gallery, formerly the Residence of John Julius Angerstein, Esq., lately pulled down. The latter was contributed to the Water-colour Society's exhibition in 1836, and went to the South Kensington Museum, together with two drawings of Lincoln Cathedral and one of Thornton Abbey, Lincolnshire. sepia drawing of Antwerp Cathedral went to the British Museum.
