GIM is an acronym that can refer to several concepts across different fields. The most widely cited is the Glashow–Iliopoulos–Maiani mechanism in particle physics.

Proposed by Sheldon Glashow, John Iliopoulos, and Luciano Maiani in the 1970s, the GIM mechanism explains the suppression of flavor-changing neutral currents in weak interactions. It achieves this through a cancellation among quark contributions when quarks come in complete generations, a feature that helped motivate the existence of the charm quark and shaped the structure of the Standard Model.

In information management, GIM often stands for Global Information Management. This usage describes practices and disciplines involved in coordinating, governing, and leveraging information resources across multinational organizations, including data governance, enterprise architectures, and cross-border data policies.

In geospatial contexts, GIM can denote Geographic or Geospatial Information Management, referring to the governance, collection, storage, and sharing of geographic data. This includes standards, interoperability, and infrastructure for GIS across agencies or partners.

Because GIM is an acronym used in multiple domains, its meaning is highly context-dependent. When encountered, the surrounding field—physics, information management, or geospatial work—usually clarifies which interpretation is intended.
