 is a Japanese-born American judoka. Matsumoto competed for the United States in the women's 48 kg judo event at the 2008 Summer Olympics.
Matsumoto, who was raised in California, is coached by her father, David Matsumoto. She began judo at the age of 5. Matsumoto won the 2004 U.S. Olympic Trials, but did not compete in the Olympics that year because the U.S. failed to earn a spot in her weight class.

At the 2008 Summer Olympics she fought against Ryoko Tani (JPN) and Wu Shugen (CHN), but lost both matches.
