Pop Rock (ポップロック, poppu rokku) (born March 19, 2001) is a Japanese racehorse trained by Katsuhiko Sumii.

On his next start, it managed to get the closest to Deep Impact in the 2006 Group 1 Arima Kinen and was beaten to second by Admire Moon in the 2007 Japan Cup.

[3][4][5] In 2010 Pop Rock was sold to new owners and was trained in Ireland by Takashi Kodama.

[3] Its final race was the Irish St. Leger but it trailed the field and was then retired to stud.
