The concepts of entrepreneurship and innovation have become increasingly pervasive in academic and policy discourses, from economic growth to societal impact and sustainability. There has been an increasing focus on gender and entrepreneurship, although questions of diversity remain under-researched in the innovation literature. In this introductory chapter, we provide an overview of the concepts of gender, diversity and innovation, before outlining the contributions comprising this edited collection. As well as setting the tone for the subsequent chapters that present a broad range of insights into women and innovation, it also introduces the importance of intersectionality as an additional barrier facing under-represented entrepreneurial innovators.
