Odd Brochmann (21 December 1909 – 27 October 1992) was a Norwegian architect, professor and children's writer.

After World War II, he was involved in building projects at Ljan and Tveita in Oslo, and the designing of social institutions nationwide.

He made a considerable effort by processing and releasing the collected material of housing surveys in Oslo in the years 1948-1961.

He discontinued his architectural practice in 1963 and settled in Copenhagen, where he worked as a writer (including for Politiken 1964-1966).

He also wrote travelogues, worked as a draftsman and as a teacher at the Royal Danish Academy of Fine Arts.
