A concourse is a place where pathways or roads meet, such as in a hotel, a convention center, a railway station, an airport terminal, a hall, or other space.

An alternate meaning now is "an open space or hall (as in a railway terminal) where crowds gather."[1] In this meaning as a place where crowds gather, while many persons in any crowd no doubt have followed different paths in their lives to get to the place, there need not be notable specific roadways leading to the place.
Examples of concourses include:
More recently, "concourse" is often used to refer to a situation where people come together in online presence, even if they do not physically come together in reality. An example of such an online community is the IEEE Student Concourse, as well as various online shopping concourses.
