This introduction builds on De Costa et al.'s (2016], [2019) notion of linguistic entrepreneurship, which is defined as "the act of aligning with the moral imperative to strategically exploit language-related resources for enhancing one's worth in the world" (2016: 696). The four empirical studies and two critical commentaries that constitute this special issue explain the relevance of this construct and explore how it is instantiated in a range of formal and informal educational contexts across the world. Specifically, we explain how linguistic entrepreneurship serves as a unique and innovative contribution to the existing body of sociolinguistics, applied linguistics, and language policy research on neoliberalism.
