Great Britain's Fleetwood finished 18-under at the Games, one shot short of Scottie Scheffler, who secured the United States' second straight gold in this event.
Fleetwood fell out of the lead with a bogey from the rough on the 17th but got up and down for par on the final hole for a 66 to seal second place, ahead of Japan's bronze medallist Hideki Matsuyama.
"There's part of me that's disappointed, of course, but at the same time I never dreamt I would be an Olympic medallist," Fleetwood said after the conclusion on Sunday.
"I haven't been in the mix that much recently and being back there, playing well and feeling how that felt again, I enjoyed it so much and I'm unbelievably proud to be an Olympic medallist.
"It feels unbelievably special and I know I didn't win gold, a very good golfer did, but standing on that podium with a medal was one of the most amazing moments I've had as a golfer.
"I'll remember those times for the rest of my life."
Jon Rahm had led for large parts, with four shots over Fleetwood when he stepped up to the tee on the 11th, only for the Spaniard to collapse in remarkable fashion.
Scheffler charged to the front with four straight birdies down the stretch, making an 18-foot birdie putt to take the lead for the first time all day with just one hole remaining.
In doing so, victorious world number one Scheffler set an Olympic record for 72 holes with his 19-under 265 at Le Golf National.
