Donald John Cameron FRIBA (10 May 1894 – 11 July 1972) was a Scottish architect, prominent in the first half of the 20th century.
He was mainly active in the west of Scotland, where he designed schools and churches, although The Building News and Engineering Journal referred to him as being of "septic tank sewage repute" in 1900.
He was also part of the architectural department of shipbuilders Alexander Stephen and Sons in Linthouse.
Two years later, he formed a partnership with Lithgows, his former employer, at 183 West George Street.
[2] At least one of Cameron's designs, the Clachan-ath-Luib War Memorial in North Uist, is now a listed structure.
