Based on current, widely cited information, the richest Dragon on Dragons’ Den is Peter Jones. He consistently appears at the top of wealth rankings among the show’s investors, with net worth figures commonly reported around or above £1 billion in recent estimates. His wealth stems from a diversified business portfolio including technology, consumer products, and media ventures, built over multiple decades of entrepreneurship.

If you’d like, I can narrow this down to the most up-to-date figure from a specific source or region (e.g., UK newspapers vs. portrait profiles) and note any recent changes to the lineup or new Dragons who might challenge the top spot.
