Peter Jones has appeared continuously since the first series of the British show Dragon's Den.
Jones joined the original Dragon's Den panel when the BBC series began in 2005 and remained a regular investor as the line-up changed. His continued presence makes him the programme's longest-serving Dragon and the only original investor to remain on the panel throughout the show's run described by the programme's standard biographies.
Peter Jones is a British entrepreneur and businessman with interests that have included telecommunications, technology, retail and leisure. On Dragon's Den, he is known for examining the size of an opportunity, the entrepreneur's valuation and the route to scaling a business. His investments and negotiations have made him one of the most recognisable figures associated with the British version.
This fact is sometimes confused with the question of who was the first Dragon to invest in a particular company. The answer here concerns continuous panel membership, not the number of deals made or the value of investments. Other long-serving Dragons, including Deborah Meaden, joined after the first series.
