The term Engineers Without Borders (EWB; French: Ingénieurs sans frontières, ISF) is used by a number of non-governmental organizations in various countries to describe their activity based on engineering and oriented to international development work. All of these groups work worldwide to serve the needs of disadvantaged communities and people through engineering projects. Many EWB national groups are developed independently from each other, and so they are not all formally affiliated with each other, and their level of collaboration and organizational development varies. The majority of the EWB/ISF organizations are strongly linked to academia and to students, with many of them being student-led.
