2017 was Fleetwood's most successful year to date. In January he won his second European Tour event, the Abu Dhabi HSBC Golf Championship, by one stroke over Dustin Johnson and Pablo Larrazábal after a final round 67. In March, Fleetwood was runner-up in the WGC-Mexico Championship, a shot behind Johnson. In April, he lost in a sudden-death playoff at the Shenzhen International to Bernd Wiesberger, at the first extra hole. Fleetwood had come from eight strokes behind on the final day with a stunning round of 63 to set the clubhouse lead. In the playoff, Fleetwood found the green in two, but Wiesberger from trouble fired an approach to within five feet and holed the birdie putt for the victory. In June, Fleetwood finished fourth in the U.S. Open, while in July, he won the Open de France, beating Peter Uihlein by a stroke, after a bogey-free final round 66. He moved from 99th in the World Rankings at the start of the year into the world top-20. In November 2017, Fleetwood won the European Tour season-long Race to Dubai and won $1,250,000 from the bonus pool.
