The wealthy investors on the UK television programme Dragon's Den are called Dragons.
The title is the programme’s central piece of branding: entrepreneurs enter the den and pitch to a panel of Dragons, each of whom may offer money in exchange for equity. The term refers to the investors collectively as well as to an individual panel member. It is not a formal financial job title.
The UK name comes from the international format’s Japanese predecessor, Money Tigers, but the British adaptation chose “Dragons” for its own investor identity. This is why the American version uses “sharks,” while the British version does not use either word as a literal description of the investors’ professions.
The panel has changed repeatedly since the programme began. Individual Dragons have included entrepreneurs from retail, technology, property, food, manufacturing, and finance, but their shared on-screen role remains deciding whether a pitch merits investment.
