Peter Jones is the longest-serving investor on the British television programme Dragons' Den.
Jones has been part of the regular British panel since the programme began in 2005. His continuing presence across the series makes him the only original dragon to remain a constant central figure through the programme's many panel changes.
He is a British entrepreneur and investor whose business interests have included technology, telecommunications, leisure and property. On the programme, he is known for examining the commercial scale of a proposal, the entrepreneur's ownership and the evidence supporting a valuation.
The distinction is sometimes confused with the title of longest-serving dragon at a particular point in the programme's history. Several investors have had lengthy runs, but Jones's tenure began with the 2005 launch and has continued through subsequent generations of the panel.
