Sayaka Yoshimura (born January 30, 1992) is a Japanese curler from Sapporo. She currently plays third for the Ayumi Ogasawara rink.

Yoshimura made her international debut for Japan at the 2006 Pacific Junior Curling Championships, playing lead for Team Japan, skipped by Megumi Kobayashi. They would win a silver medal. Yoshimura did not return to the Pacific Juniors until 2011, when she skipped Japan to a gold medal at the 2011 Pacific Junior Curling Championships, qualifying her nation for the 2011 World Junior Curling Championships. There, she led Japan to a 3-6 record in 8th place. Also that season, she skipped Japan at the 2011 Winter Universiade, finishing 4th place.

Yoshimura would once again lead Japan to a gold medal at the Pacific Juniors in 2012. She would then lead the team to a 5th place (6-4) finish at the 2012 World Junior Curling Championships. She won another gold medal for Japan at the 2013 Pacific-Asia Junior Curling Championships. She would finally make the podium at the World Juniors, leading Japan to bronze medal at the 2013 World Junior Curling Championships. After the round robin, her team of Rina Ida, Risa Ujihara and Mao Ishigaki were in 2nd place with a 6-3 record. However, they lost both of their playoff games before beating the Czech Republic in the bronze medal game.

One year out of juniors, her team stuck together and played at the 2013 Winter Universiade, finishing in a disappointing 7th place. After the season, Yoshimura joined the Ogasawara rink. On the World Curling Tour, they would win two events, the Prestige Hotels & Resorts Curling Classic and the Hub International Crown of Curling. At the 2014 Pacific-Asia Curling Championships, they would pick up a bronze medal. This would ordinarily not be enough to qualify Japan for the World Championships, but because Japan is hosting the event, the team will represent their country at the 2015 World Women's Curling Championship, Yoshimura's first Worlds.
