The concept of a groupoid is a very general one, abstracting and generalizing many different concepts and definitions, including groups, group actions, equivalence relations, vector bundles, fundamental groups, and many others. I will define groupoids and give many examples, and then discuss the notion of "groupoid objects" in a category, which is the analogue of the notion of a "group object". Examples include Lie groupoids, symplectic groupoids, and algebraic groupoids.
