The concept of the policy entrepreneur lends itself to analysing how actors at the international level draw attention to problems, advance workable proposals, and link outcomes to symbolic values. The international space is a challenging arena for policy advocacy, as it lacks the oversight and well-established systems of policy development commonly found at the national or sub-national level. Policy entrepreneurs acting in the international space face obstacles and opportunities different from their domestic counterparts, particularly in the realms of policy initiation, mediation, and compromise. Here, we distinguish the actions of international policy entrepreneurs from the international engagements of state-based, government actors, the actions of international organizations, and those of civil society advocacy groups. Two examples of international policy entrepreneurship are given. We complete the chapter with an analytical framework to guide future research on international policy entrepreneurship.
