The pressing environmental crises of the Anthropocene are inherently connected to ocean health. Yet, the oceans are currently in a critical state. The article explores the idea of giving rights to oceans as one way to enhance their legal protection. It draws on scholarship and practice regarding the existing legal rights of nature, and discusses the challenges and prospects of ocean rights. In doing so, the article raises and addresses three fundamental questions for the recognition of such rights: first, why oceans should hold their own rights in the first place; second, who, i.e. what exact entity or entities, shall hold ocean rights; and finally, how such rights could be implemented and represented and thus be given practical effect.
