International Student Ministry (ISM) refers to evangelical Christian ministry among international students within an academic context, often carried out by Protestant college religious organizations, volunteers and churches. It is considered part of the church's mission, within the broader framework of diaspora missions. The first two decades of the 21st century have seen a sharp growth in the number of international students globally with a corresponding development in ISM.

International students, or foreign students, are students who undertake all or part of their tertiary education in a country other than their own.
