Pro-Israel Lobby is a collective term for organisations that advocate for policies supporting Israel's interests in foreign political contexts. These groups engage in lobbying efforts to influence governmental and public opinion, aiming to secure favourable diplomatic, economic, and military support for Israel. Their activities are often concentrated in countries with significant geopolitical influence, such as the United States and European nations, where they work to shape foreign policy decisions that align with Israel's strategic goals.

The Pro-Israel Lobby is significant because it plays a crucial role in shaping foreign policy decisions that impact international relations. By advocating for Israel's interests, these organisations influence diplomatic and military support, affecting regional stability in the Middle East. Their efforts can lead to shifts in alliances and global political dynamics, highlighting their strategic importance.

Scholars of international relations argue that the Pro-Israel Lobby exemplifies how non-state actors can influence state policies, particularly in democracies where lobbying is a key component of the political process. This influence underscores the complex interplay between domestic politics and international diplomacy, as lobbying efforts can alter the trajectory of bilateral and multilateral relations.
