Workforce broke the track record with a blistering turn of foot as he won the 231st running of the Derby by seven lengths at Epsom.
The breathtaking victory in baking sunshine sealed a Classic double for champion jockey Ryan Moore after his Oaks win on Snow Fairy.
It was the fifth victory in the race for Newmarket trainer Sir Michael Stoute as Workforce finished ahead of 100-1 shot At First Sight with Frankie Dettori third on 9-2 chance Rewilding.
Derby win 'special' for jockey Moore
Pacemaker At First Sight, the outsider of Aidan O'Brien's three runners, tried to steal the race but was reeled in by Dante Stakes runner-up Workforce.
Moore was delighted with his mount and told BBC Sport: "We had a really clean run. He quickened up really well and he kept extending. He's a really good horse and I'm delighted.
"He was awesome. He travelled beautifully. It's a very special day. I was delighted to win the Oaks but this is the most important race for me and to win it for the boss (Stoute) too is even more special."
The horse is owned by Prince Khalid Abdulla, a first cousin to King Abdullah of Saudia Arabia, who has won the Derby before with Quest for Fame (1990) and Commander in Chief (1993).
Stoute has won the Derby with Shergar (1981), Shahrastani (1986), Kris Kin (2003) and North Light (2004).
The 64-year-old trainer added: "He was seriously good today. I think he has won one of the great Derbies in terms of the performance. I'm thrilled for Ryan.
