Duncan Bannatyne was the Dragons' Den investor associated with the surname Bannatyne.
Bannatyne joined the British investment panel in the programme's early years and became one of its most recognisable figures. He built his business career through ventures including care homes, health clubs and hotels, and his direct questioning became a familiar part of the show's format.
His background differed from that of some other Dragons. While several investors were strongly associated with retail, fashion or technology, Bannatyne was widely identified with leisure, fitness and care businesses. That experience shaped the types of companies he examined during pitches.
The investor's name is sometimes confused with the programme title because both contain the word “Bannatyne” in public discussion of his wider business empire. However, the show itself is titled Dragons' Den, while Bannatyne is the surname of one particular Dragon. He left the regular panel after the 2014 series.
