Ashima Shiraishi (born April 3, 2001 in New York, NY) is an American rock climber. Ashima started climbing at the age of six at Rat Rock in Central Park, joining her father. Only a few years later, she quickly established herself as one of the top boulderers and sport climbers in the world, and is nowadays widely considered to be the best teenage climber of either gender. Her numerous accolades include first-place finishes in international competitions, and multiple first female and youngest ascents. Ashima is featured in several short documentary-style films, and is the subject of the documentary short "Return to the Red" (2012).
The New York Times referred to her as a "bouldering phenom". Outside Magazine described her as a "young crusher". At age 13 she became the second female, and youngest person, to climb a sport route with a difficulty grade of 5.14d/5.15a (9a/9a+). In 2016, she achieved the second ascent of the V15 Horizon in Mount Hiei, Japan and became the first female climber to climb the grade.
