Stone Island is an Italian luxury fashion house specialised in men's apparel, outerwear, and accessories headquartered in Ravarino, Emilia-Romagna.

Its core branding includes a nautical star and compass, both of which is printed or overlaid atop a button-on cloth badge with green, yellow, and black detailing.

[2][3] It is a global staple of youth subculture as characterized by Italian Paninaro, English football casuals, British, American, and Canadian hip hop culture, as well as world-wide streetwear.

In 2017, Singaporean sovereign wealth fund Temasek Holdings bought out a 30% stake in Stone Island valued at €345 million.

[9][10] Three years later, Italian fashion house Moncler bought a majority stake in Stone Island for a reported €1.15 billion.

[13][14] According to founder Massimo Osti, his novels' exploration of "boats and sea" moved him to create a brand with "[a] new sensibility oriented to science instead of fashion".

[5] Magazine i-D described Stone Island as a high-end status symbol among youth who show off the compass logo in a practice known as "getting the badge in".
