PARIS, France — The Summer Olympics are underway as thousands of athletes prepare to go for gold in Paris.
The United States leads the world by far in most gold medals won in history, but a select few athletes who were — or still are — superstars in their sport carry a few more than most.
Some of these current record-holders competing in Paris this year and could increase their medal count.
Here are the Americans who have won the most gold medals of any U.S. Olympians.
Michael Phelps: 23 gold medals
The world's most decorated Olympian, Michael Phelps dominated the swimming world until his retirement in 2016.
Phelps qualified for his first Olympics in 2000 at age 15, and by 2004 he was tying world records, winning eight medals at a single Games with six gold and two bronze. In 2008, he won his most medals yet, taking home eight golds, breaking another Olympic record. Phelps continued to rack up gold medals at the 2012 and 2016 Olympics for a total of 23.
Mark Spitz: 9 gold medals
Swimmer Mark Spitz kicked off his Olympic career with two team golds in 1968. Four years later, he was the most successful athlete at the 1972 Munich Games, winning seven gold medals in swimming, a record that held until Michael Phelps overtook it in 2008.
Carl Lewis: 9 gold medals
Carl Lewis, a track and field superstar, is one of only a handful of Olympians to win a gold medal in the same individual event in four consecutive Olympic Games. The sprinter and long jumper won four golds at the 1984 Los Angeles Games, two in Seoul in 1988 and two at the 1992 Barcelona Games. His final gold medal win was in the long jump at the 1996 Summer Olympics in Atlanta.
Katie Ledecky: 9 gold medals
A powerhouse in the pool, Katie Ledecky won a gold medal at 15 years old in her Olympic debut at the London Games in 2012.
Now known for smashing world records and often beating her competitors by huge margins, the 27-year-old American headed to Paris looking to add to her six individual Olympic gold medals. She picked up another - her eighth total gold medal - in the 1,500-meters. She won another by holding off Ariarne Titmus to win the 800-meter freestyle.
With her win in the 800-meter, she passed Jenny Thompson's record for the most gold medals held by an American woman.
She became only the sixth Olympian to reach nine gold medals, joining swimmer Mark Spitz, track star Carl Lewis, Soviet gymnast Larisa Latynina and Finnish runner Paavo Nurmi in a tie for second place.
She also joined Phelps as the only swimmer to win the same event at four straight Olympics.
Caeleb Dressel: 9 gold medals
Caeleb Dressel only knows the top of an Olympic podium in his decorated career. In Paris, he anchored the winning 4x100-meter freestyle foursome as the Americans beat out the rival Australians for his eighth gold.
While Dressel failed to defend his golds from the Tokyo Olympics in the 100 butterfly and 50 freestyle, he did pick up a ninth gold medal. Dressel swam on the U.S. team during the prelims for the mixed 4x100m medley relay. While he wasn't part of the team who swam in the final and set a new world record, Dressel still gets a gold medal because of his participation in the previous heat.
Of his nine gold medals, six of those have been in relay events.
The 27-year-old American was a standout at the Tokyo Olympics, capturing five gold medals, but burnout led him to walk away from the sport in the middle of the 2022 world championships. After an extended break, he failed to qualify for the 2023 worlds.
Jenny Thompson: 8 gold medals
Jenny Thompson has won the most gold medals of any American woman. The swimmer competed in the 1992, 1996, 2000, and 2004 Summer Olympics, earning all eight of her gold medals in relay events. With 12 total medals across four Olympic Games, she has more swimming medals than any other female Olympian.
Matt Biondi: 8 gold medals
Swimmer Matt Biondi took home five gold medals at the Seoul Games in 1988, setting multiple world records in the process. Biondi competed in the Summer Games in 1984, 1988 and 1992.
Ray Ewry: 8 gold medals
Ray Ewry overcame polio as a boy to become a dominant track and field jumper, setting records in the standing jumps that held for decades. He won three gold medals at the 1900 Paris Games, three gold medals at the 1904 London Games, and two gold medals at the 1908 St. Louis Games.
Allyson Felix: 7 gold medals
Runner Allyson Felix is the most decorated woman in Olympic track and field history, with seven gold medals and 11 total from five consecutive Summer Games.
With six relay wins in 2008, 2012, 2016 and 2020 and one individual gold in 2012, Felix was the first female track and field athlete ever to win seven Olympic gold medals.
Simone Biles: 7 gold medals
Biles, widely considered the greatest gymnast of all time, now has nine Olympic medals, including seven gold medals across her three Summer Games appearances and could still add even more.
She made her debut in Rio and won four gold medals, including team and individual all-around, and one bronze. Biles returned for the Tokyo Olympics, where she won silver in the team competition and bronze on the balance beam.
So far in Paris, she won gold in the team event, the individual all-around and the vault.
The 27-year-old is scheduled to compete in two more events: Balance beam and floor exercise.
