Maritime piracy and armed robbery threaten seafarers and the global supply chains that move essential goods. On this page, we map where incidents concentrate, look at the human toll on crews, and connect those patterns to regional security and governance. You’ll also see how anti-piracy practices and naval presence have changed outcomes over time, including in high-risk areas.
