A homotopy quotient is a quotient (say of a group action) in the context of homotopy theory.
Just as a quotient is a special case of colimit, so a homotopy quotient is a special case of homotopy colimit.
The homotopy quotient of a group action may be modeled by the corresponding action groupoid, which in the context of higher geometry means the corresponding quotient stack.
In type theory/homotopy type theory the analogous concept is that of quotient types.
