Bruce Campbell (15 June 1912 – 9 January 1993) was an English ornithologist, writer and broadcaster, closely associated with the British Trust for Ornithology (BTO).
After education at Winchester College, he studied at the University of Edinburgh, obtaining a BSc in biology.
He later gained a doctorate in comparative bird studies, so becoming one of the first field naturalists to also be a trained scientist.
After World War II, he brought the work of sound recordist Ludwig Koch to the attention of the BTO.
He conducted a pioneering study of the pied flycatcher at the Nagshead woodland reserve, Gloucestershire.
