Quiksilver is a brand of surf-inspired apparel and accessories that was founded in 1969 in Torquay, Australia, but is now based in Huntington Beach, California. It is one of the world's largest brands of surfwear and boardsport-related equipment.

The Quiksilver brand's logo, designed in 1973 by founders Alan Green and John Law, was inspired by Japanese painter Hokusai's woodcut, The Great Wave off Kanagawa. It depicts a large wave with a mountain on a red background.
