For other uses, see OBJ (disambiguation).

OBJ is a programming language family introduced by Joseph Goguen in 1976.

A family of declarative "ultra high-level" languages. Abstract types, generic modules, subsorts (subtypes with multiple inheritance), pattern-matching modulo equations, E-strategies (user control over laziness), module expressions (for combining modules), theories and views (for describing module interfaces). For the massively parallel RRM (Rewrite Rule Machine).

Important members of the OBJ family of languages include CafeOBJ, Eqlog, FOOPS, Kumo, Maude and OBJ3.
