Object REXX is a high-level, general-purpose, interpreted, object-oriented (class-based) programming language.

It is a follow-on and a significant extension of the Rexx programming language (often called "Classic Rexx"). Object REXX retains all the features and syntax of "Classic Rexx" while adding full object-oriented programming (OOP) capabilities. Although Object REXX does not implement all aspects of the "Information Technology – Programming Language REXX" ANSI X3.274-1996^[1] standard, it offers many new features of its own.

Following its "Classic Rexx" influence, Object REXX is designed to be easy to learn, use, and maintain. Several object-oriented implementations of REXX are available, including Open Object Rexx ("ooRexx") and Rexx Object Oriented ("roo!").^[2]^: 311
